Hurricanes


More than 6.6 million homes on the Atlantic and Gulf coasts are at risk of hurricane-driven storm surge with a total reconstruction cost value (RCV) of nearly $1.5 trillion.

The latest annual analysis from CoreLogic finds that the Atlantic Coast has more than 3.8 million homes at risk of storm surge in 2015 with a total projected reconstruction cost value of $939 billion, while the Gulf Coast has just under 2.8 million homes at risk and nearly $549 billion in potential exposure.

Which states have the highest total number of properties at risk?

Six states—Florida, Louisiana, New York, New Jersey, Texas and Virginia—account for more than three-quarters of all at-risk homes across the United States. Florida has the highest total number of properties at various risk levels (2.5 million), followed by Louisiana (769,272), New York (464,534), New Jersey (446,148), Texas (441, 304) and Virginia (420,052).

But if you rank the states by the highest total projected reconstruction costs in 2015, the top five are: Florida ($491.1 billion), New York ($177.4 billion), Louisiana ($162.1 billion), New Jersey ($126.8 billion) and Virginia ($91.1 billion).

CoreLogic makes the point that even though Louisiana has the second highest number of homes at risk to storm surge in 2015, only one-quarter are in the extreme or very high storm surge category, due in large part to the upgrade and expansion of levees in the state in the 10 years since Hurricane Katrina.

As Dr. Tom Jeffery, senior hazard risk scientist for CoreLogic says:

The number of hurricanes each year is less important than the location of where the next hurricane will come ashore. It only takes one hurricane that pushes storm surge into a major metropolitan area for the damage to tally in the billions of dollars. With new home construction, and any amount of sea-level rise, the number of homes at risk of storm surge damage will continue to increase.”

CoreLogic’s analysis comes as the National Hurricane Center (NHC) debuts experimental storm surge watch and warning graphics for the 2015 hurricane season:

Storm surge is often the greatest threat to life and property in the event of a hurricane. While most coastal residents can remain in their homes and stay safe from a storm’s winds, evacuations are generally needed to keep people safe from storm surge, the NHC says.

It’s important to note that many properties located outside designated FEMA flood zones are still at risk for storm surge damage.

As CoreLogic reminds us, homeowners who live outside the FEMA flood zones frequently do not carry flood insurance, given that there is no mandate to do so, and therefore may not be aware of the potential risk storm surge poses to their properties.

By now you’ll have read the latest forecasts calling for a below-average Atlantic hurricane season.

NOAA, Colorado State University’s Tropical Meteorology Project, North Carolina State University, WSI and London-based consortium Tropical Storm Risk all seem to concur in their respective outlooks that the 2015 hurricane season which officially begins June 1 will be well below-norm.

TSR, for example, predicts Atlantic hurricane activity in 2015 will be about 65 percent below the long-term average. Should this forecast verify, TSR noted that it would imply that the active phase for Atlantic hurricane activity which began in 1995 has likely ended.

Still it’s important to note that the forecasts come with the caveat that all predictions are just that, and the likelihood of issuing a precise forecast in late May is at best moderate. In other words, uncertainties remain.

These are wise words.

A recent report by Karen Clark & Co pointed to the rising vulnerability of the U.S. to hurricanes and other coastal hazards because of increasing concentrations of property values along the coast.

Of the $90 trillion in total U.S. property exposure, over $16 trillion is in the first tier of Gulf and Atlantic coastal counties, an increase from $14.5 trillion in 2012, KCC said.

KCC then superimposed 100 year U.S. hurricane events on the 2014 property values in its database. The result was that three regions—Texas, Florida and the Northeast—emerge as the most likely for mega-catastrophes.

In all of these regions, the largest losses from the 100 year hurricanes making landfall near Galveston-Houston, Miami and Western Long Island, are much larger than the 100 year PMLs (Probable Maximum Losses).

As insurance industry execs know, it only takes one hurricane to make landfall for a below-average season to become active and record losses to ensue. Here’s a visual of what the 1992 season—the year of Hurricane Andrew—looked like, courtesy of Weather Underground:

Just in time for the peak of hurricane season, our updated paper on the residual property market is hot off the press.

At first glance the numbers on the property insurance provided by the nation’s FAIR and Beach and Windstorm plans indicate that attempts by certain states to reduce the size of their plans appear to be paying off.

As you’ll see, the exposure value of the residual property market in hurricane-exposed states has declined significantly from the peak levels seen in 2011. In fact between 2011 and 2013, total exposure to loss in the plans fell by almost 30 percent – from $885 billion to $639 billion.

Why such a drop?

Florida Citizens, a plan that accounts for more than half (51 percent) of the total FAIR Plans’ exposure to loss, saw its exposure drop by nearly 50 percent from $429.4 billion in 2012 to $228.9 billion in 2013, as Citizens took much-needed steps to reduce its size.

This accounted for the overall reduction in total exposure under the FAIR plans. In 2013 total exposure to loss in the FAIR Plans was $445.6 billion, a 38 percent drop from its 2011 peak of $715.3 billion.

But what of the Beach and Windstorm plans?

Latest data show that between 2011 and 2013 exposure to loss in the Beach and Windstorm Plans actually grew by 14 percent.

Five state Beach and Windstorm plans are covered in our report: Alabama, Mississippi, North Carolina, South Carolina and Texas.

Over a longer time period, 2005 to 2013, the I.I.I. finds that some of the Beach and Windstorm plans saw accelerating growth. For example, total exposure to loss in the Texas Beach Plan (the Texas Windstorm Insurance Association (TWIA)) increased by 230 percent during this period.

A plan that would move TWIA’s policies over to private insurers and depopulate its book of business (much like Florida Citizens has done) is in the works, but so far nothing definite.

An ongoing and arguably more pressing concern is the fact that many of the residual market plans charge rates that are not actuarially sound and do not accurately reflect the risk of loss.

What does this mean? The I.I.I. warns that a major hurricane could expose residents in certain states to billions of dollars in post-storm assessments:

While hurricane activity in the most exposed states may have been lower in recent years, there is no question that over the long-term major hurricanes will cause extensive damage in future. This highlights how important it is for the rates charged by these plans to be actuarially sound.”

Forecasters’ Twitter feeds are alight this morning as to the potential development of two systems in the tropical Atlantic.

Here’s the latest graphic of where they’re located, courtesy of the National Hurricane Center (NHC):

The NHC gives the first disturbance currently located several hundred miles east of the southern Windward Islands a 50 percent chance of tropical cyclone formation in the next five days.

The second disturbance, a tropical wave located 1,000 miles east of the Lesser Antilles, has a low (20 percent) chance of tropical storm formation in the next five days.

Over at Weather Underground, Dr. Jeff Masters noted that if the first disturbance (designated Invest 96L by the NHC) does develop, it would likely be similar to Tropical Storm Bertha of early August while it is in the Caribbean—a weak and disorganized system that struggles against dry air.

Meanwhile @EricHolthaus tweets that Invest 96L could be a tropical threat to the U.S. next week, based on the first model runs.

It’s still too early to tell, but Hurricane Hunters are on call to investigate 96L Thursday afternoon if necessary.

Forecasters with NOAA’s Climate Prediction Center now say the chances of a below-normal Atlantic hurricane season have increased to 70 percent, up from 50 percent in May.

In its updated outlook, NOAA said overall atmospheric and oceanic conditions that are not favorable for storm development will persist through the season.

Check out the revised numbers in this NOAA graphic:

However, coastal residents may want to heed the words of NOAA lead forecaster Dr. Gerry Bell:

Tropical storms and hurricanes can strike the U.S. during below-normal seasons, as we have already seen this year when Arthur made landfall in North Carolina as a category-2 hurricane. We urge everyone to remain prepared and be on alert throughout the season.”

This echoes the warning of others. After all, it only takes one landfalling hurricane for a season to go from below-active to active for coastal residents.

In a recent post Weather.com gave the classic examples of 1992 and 1983:

The 1992 season produced only six named storms and one subtropical storm. However, one of those named storms was Hurricane Andrew, which devastated South Florida as a Category 5 hurricane. In 1983 there were only four named storms, but one of them was Alicia. The Category 3 hurricane hit the Houston-Galveston area and caused almost as many direct fatalities there as Andrew did in South Florida.”

The $15.5 billion in estimated property losses ($23.4 billion in 2013 dollars) paid out by insurers for Hurricane Andrew ranks second in a PCS chart via the I.I.I. of the 10 most costly hurricanes in U.S. history, after Hurricane Katrina in 2005.

If Hurricane Andrew were to occur today, Karen Clark & Company estimates insured property losses would total $57 billion, based on current exposures.

As we head into August and the weekend, here are some of the stories from around the insurance blogosphere that piqued our interest:

Bertha: Tropical storm warnings have been issued for Puerto Rico, the U.S. and British Virgin Islands and other nearby islands as Tropical Storm Bertha – the second named storm of the 2014 Atlantic hurricane season – approaches the Caribbean. Early Friday, the National Hurricane Center (NHC) reports that Bertha’s winds are near 45 mph with no significant change in strength expected in the next few days. The latest 5-day forecast track for Bertha via the NHC has it staying well off the U.S. East Coast – let’s hope it stays that way.

Commercial Rate Increases Slow: Prices for commercial property/casualty insurance continued to slide in the second quarter of 2014, according to the latest quarterly survey from the Council of Insurance Agents & Brokers. On average, prices for small, medium and large accounts eased by a modest -0.5 percent during the second quarter, compared with 1.5 percent in the first quarter. Competition continued to drive the market, the Council said. Of note, pricing for property fell into negative territory with a -2.6 percent drop last quarter compared with flat pricing in the first quarter.

Some 6.5 million U.S. homes with a total reconstruction value of nearly $1.5 trillion are at risk of damage from hurricane-driven storm surge, and more than $986 billion of that risk is concentrated in 15 metro areas, according to an annual report by CoreLogic.

The 2014 analysis by CoreLogic found that by state, Florida ranks number one for the number of homes at risk, with nearly 2.5 million homes and $490 billion in total projected reconstruction costs.

At the local level the New York metropolitan area (including northern New Jersey and Long Island) contains not only the most number of homes at risk for potential storm surge damage (687,412), but also the highest total reconstruction value of residential homes exposed, at more than $251 billion.

Ranked second among the major metropolitan areas at risk is Miami, Florida with 562,410 homes exposed and a total reconstruction value of $103.2 billion, followed by Tampa, Florida with 444,765 homes at risk and a total reconstruction value of $79.1 billion.

CoreLogic makes the point that just one storm of sufficient intensity occurring in or near one of the major metropolitan areas in the report is all that would be needed to cause tens of billions in property damage:

Past hurricane seasons have demonstrated the impact that just one storm of sufficient severity, located in exactly the wrong place, can achieve. Andrew, Katrina, and finally Sandy are still reminders that it takes no more than one hurricane roaring through a metropolitan and densely populated area to cause widespread property damage and threaten lives.”

CoreLogic goes on to explain that extensive regions along both the Gulf and Atlantic Coasts are vulnerable to storm surge, and yet many of the homeowners who live in these areas are not required to carry flood insurance because they are not located within a designated FEMA 100-year floodplain.

Since standard homeowners insurance excludes flood losses from either fresh or salt water, homeowners who are not located in FEMA Special Flood Hazard Areas, but are in high-risk surge zones, often do not consider buying National Flood Insurance Program (NFIP) coverage for their properties.”

If a strong hurricane were to pass through the Gulf of Mexico the overall effect on U.S. oil and natural gas supply would not be as severe as in past years, due to declining production in the region, according to a report from the U.S. Energy Information Administration (EIA).

However, Artemis blog warns that this won’t change the potential impact to insurers and reinsurers, particularly with the removal and decommissioning of rigs also being insured.

In its post, Artemis notes that the reinsurance and insurance-linked securities (ILS) market in recent years has been placing an increasing focus on gaining access to underwriting energy risks, particularly physical damage risks due to storms and earthquakes.

With an increasing amount of ILS capital at risk in the Gulf of Mexico, as well as on the shore through catastrophe bonds and collateralized reinsurance, the exposure to hurricane impacts on the oil and gas production network in and around the Gulf is growing.”

The EIA estimates that up to 11.6 million barrels of crude oil and 29.7 billion cubic feet of natural gas production could be disrupted by storms during the 2014 Atlantic hurricane season. Its estimate is based on NOAA’s Atlantic Hurricane Season Outlook released May 22.

NOAA expects that 8 to 13 named storms are likely to form within the Atlantic Basin over the next six months, including 3 to 6 hurricane, of which 1 to 2 will be intense.

In recent years offshore energy production has experienced relatively minor disruptions due to tropical weather, the EIA reports. However, a single strong storm can cause significant levels of shut-in production:

During September of 2008, category-4 hurricanes Gustav and Ike at one point caused nearly 100 percent of production capacity to be shut in. EIA estimates that these two storms (along with a tropical storm in July) resulted in the loss of 25 percent of the GOM crude oil and natural gas that would have been produced during the 2008 hurricane season.”

With just over a week to go until the start of the 2014 Atlantic hurricane season, NOAA’s outlook is hot off the press and garnering a lot of attention.

Here’s NOAA’s take on the season by the numbers:

● NOAA is calling for a 50 percent chance of a below-normal season, a 40 percent chance of a near-normal season, and only a 10 percent chance of an above-normal season.

● NOAA predicts a 70 percent likelihood of 8 to 13 named storms (winds of 39 mph or higher), of which 3 to 6 could become hurricanes (winds of 74 mph or higher), including 1 to 2 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).

● These numbers are near or below the seasonal averages of 12 named storms, six hurricanes and three major hurricanes, based on the average from 1981 to 2010.

What are the reasons behind NOAA’s predictions for a near-normal or below-normal season?

A key driver of this year’s outlook is the anticipated development of El Niño this summer that is expected to cause stronger wind shear which reduces the number and intensity of tropical storms and hurricanes.

Cooler Atlantic Ocean temperatures this season also suggest fewer hurricanes, NOAA says.

Despite the prognosis for a below-normal or near-normal season, it’s important that coastal residents don’t underestimate the hurricane threat. As Dr. Kathryn Sullivan, NOAA administrator says:

Even though we expect El Niño to suppress the number of storms this season, it’s important to remember it takes only one land falling storm to cause a disaster.”

Note: NOAA’s seasonal hurricane outlook is not a hurricane landfall forecast and does not predict how many storms will hit land or where a storm will strike.

Hurricane forecasters are sounding a warning bell for the U.S. East coast in their latest predictions for the 2014 hurricane season, even as overall tropical storm activity is predicted to be much-less than normal.

WeatherBell Analytics says the very warm water off of the Eastern Seaboard is a concern, along with the oncoming El Niño conditions.

In its latest commentary forecaster Joe Bastardi and the WeatherBell team notes:

We think this is a challenging year, one that has a greater threat of higher intensity storms closer to the coast, and, where like 2012, warnings will frequently be issued with the first official NHC advisory.”

WeatherBell Analytics is calling for a total of 8 to 10 named storms, with 3-5 hurricanes and 1-2 major hurricanes.

According to WeatherBell, there have been plenty of El Niño years with high impact seasons for the U.S. coast: 1957, 1965, 1969, 1976, 1983 (fading but still there), 1991, 1992, 2002, and 2004.

The forecasters say this pattern favors stronger storms (relative to normals) in-close to the U.S. rather than in the deep tropics which will have less to much-less than normal activity this year.

There is nothing to prohibit another Sandy-type hit from the southeast or three storms up the East Coast in one year despite a relatively low number of named storms in a season.”

Check out this post by Eric Holthaus over at Slate’s Future Tense blog for his take on how this year’s El Niño could grow into a monster.

Meanwhile, London-based consortium Tropical Storm Risk (TSR) has lowered its forecast and predicts Atlantic hurricane activity in 2014 will be about 25 percent below the 1950-2013 long-term norm and about 40 percent below the recent 2004-2013 10-year norm.

In its updated forecast TSR is calling for 12 named storms, 5 hurricanes and 2 major (Category 3 and higher) hurricanes.

TSR says two key factors in its forecast for below-normal activity are: lighter trade winds over the Caribbean and North Atlantic coinciding with the likely development of a moderate El Niño; and cooler than normal sea surface temperatures in the tropical North Atlantic.

TSR says both these predictors will have a moderately suppressing effect on activity.

A post over at Artemis blog points out that while El Niño typically results in a below average hurricane season in terms of the number of storms that form, that is no guarantee of a benign season in terms of catastrophic losses as that is down to the strength or severity and path of any storms that do form.

Updated forecasts will be released around June 1, when hurricane season opens.
