U.S. Drought Monitor Update for October 11, 2016

October 11, 2016, U.S. Drought Monitor Map

According to the October 11, 2016, U.S. Drought Monitor, moderate to exceptional drought covers 20.1% of the contiguous United States, an increase from last week’s 19.4%. The worst drought categories (extreme to exceptional drought) also increased from 3.1% last week to 3.5%.

This U.S. Drought Monitor week began with a warm high pressure ridge over the eastern contiguous United States and a colder low pressure trough dominating the West. As the week progressed, the upper-level trough dragged a cold front to the East as it migrated in the jet stream flow, and Hurricane Matthew inundated the Southeast Coast with flooding rains. Matthew eventually merged with the front as it moved up the Atlantic coast and out to sea.

Weekly precipitation was above normal due to fronts in the northwestern and central parts of the country, where drought contracted, and above normal along the Southeast Coast from tropical rains. Precipitation was below normal across the rest of the contiguous United States, with drought expanding or intensifying across the Deep South and parts of the Northeast. Temperatures averaged warmer than normal east of the Plains and cooler than normal west of the Plains.
