Droughts and Heat Waves

Droughts and Heat Waves

As of October 21, 2014, 44 percent of the contiguous 48 states was experiencing drought; 9 percent was in extreme and exceptional drought. The National Oceanic and Atmospheric Administration’s latest seasonal assessment, issued on October 16, indicates that drought intensity remained steady across California where nearly 60 percent of the state is designated as being in exceptional drought (D4) by the U.S. Drought Monitor (USDM). However, coastal northern California is expected to experience improvement, most likely in December or January. Drought is expected to persist across the remainder of California including the Sierras. Much of the Pacific Northwest is designated as being in moderate to extreme drought, according to the USDM. Drought improvement is expected for southwest Oregon but is expected to persist in the central and eastern areas of Oregon and Washington. Drought is expected to persist for most of Idaho, Nevada and Utah and is expected to develop across northern Idaho and extreme western Montana. Conditions are expected to improve in extreme southern Nevada and southern Utah.

On January 20, 2014 California Governor Jerry Brown declared a state of emergency in response to the worst drought conditions in California in a century. The drought, which is technically in its third year, was exacerbated by a lack of precipitation along the West Coast last winter, which is normally the rainy season.
