U.S. Drought Monitor Update for November 1, 2016

November 1, 2016, U.S. Drought Monitor Map

According to the November 1, 2016, U.S. Drought Monitor, moderate to exceptional drought covers 26.8% of the contiguous United States, an increase from last week’s 23.9%. The worst drought categories (extreme to exceptional drought) also increased from 4.1% last week to 4.9%.

Subtropical high pressure, in combination with ridges at the jet stream level, continued to keep much of the contiguous United States warmer and drier than normal this U.S. Drought Monitor week, while troughs and frontal systems moved in the jet stream flow across the northern contiguous United States. The hotter- and drier-than-normal conditions expanded and intensified drought in the South to Midwest and Central Rockies to Central Plains. Pacific weather systems once again brought above-normal precipitation to much of the Pacific Northwest and Far West, nibbling at the western drought areas, while cool fronts and low pressure systems brought above-normal precipitation to parts of the Upper Mississippi Valley to Northeast.

The full U.S. Drought Monitor weekly update is available from Drought.gov.
