Other notable highlights from the report
Wildfires roared across the landscape:
As of May 31, the largest fire in New Mexico history, the Hermits Peak Fire, had consumed more than 315,000 acres and was 50% contained. Across all 50 states, 1.9 million acres have burned from January 1 through June 2 — more than twice the average for this time of year.
Drought improved overall, with exceptions:
According to the May 31 U.S. Drought Monitor reportoffsite link
, 49.3% of the contiguous U.S. was in drought, down about 4.5% from the beginning of May. Areas of the Pacific Northwest, northern Rocky Mountains and High Plains saw drought conditions improve over the month of May while drought intensified or expanded across the Southwest, West and parts of the Northeast.
A stormy May with fewer tornadoes:
Several rounds of severe weather hit the U.S. during May, producing 196 preliminary tornado reports. This is 71% of the 1991-2010 average for tornadoes for the month of May (276). On May 4, severe storms formed across the central Plains and produced several tornadoes including an EF3 tornado near Lockett, Texas. A line of severe storms, also known as a derecho, barreled across the central Plains into the Upper Midwest on May 12, causing extensive damage from at least 13 tornadoes and straight-line winds.
