Natural disasters can be devastating to businesses. While damage caused by some types of natural events—such as lightning or wind—will usually be covered by commercial property insurance, you need a special policy if you want protection from flood damage. This Q&A will help you understand this type of coverage and determine whether your business needs it.

Aside from the danger of flooding, heavy rainfall can also lead to mudflow, basically creating a river of mud; and landslides, which are caused by the movement of the destabilized land—due either to gradual erosion or an accumulation of water.

Don’t confuse mudflows with mudslides as there are distinct differences.  Mudslides occur when a mass of earth or rock moves downhill, propelled by gravity. They typically don't contain enough liquid to seep into your home, and they aren't eligible for flood insurance coverage. In fact, mudslides are not covered by any policy.

When atmospheric conditions are right, tornadoes can strike with little warning and cause grave amounts of damage in a very short time. These tips can help minimize your risk and keep you and your family safe.

Protecting yourself and your family

• Keep calm. Stay in your shelter until after the storm is over.
• Check people around you for injuries. Begin first aid or seek help if necessary.
• When you go outside, watch out for downed power lines.

Protecting your property

• Make temporary repairs to prevent further loss from rain, wind or looting. These costs are reimbursable under most policies so keep the receipts.

Each year, about 1,200 tornadoes with wind speeds as high as 300 mph touch down in the United States. Though potentially not as damaging as hurricanes, tornadoes are more frequent. They can cause severe damage over a small area and, particularly before the advent of tornado warnings, many deaths. In the decade, 1965-1974, they were responsible for an average of 141 deaths each year, compared with 57 in the 10 years 1995-2004. The peak of the tornado season is April through June or July.

Warnings/watches

Remember that a watch means that weather conditions are favorable for tornadoes and a warning means one has been spotted in your area.
