A warm and dry week in the West and Plains led to more degradations. Areas of Extreme Drought (D3) expanded in the Northern Plains, and Exceptional Drought (D4) developed in Oregon for the first time since 2015. Conditions in California are also troublesome. The state has had back-to-back dry years, the wet season is over, and this water year is tied as the third driest on record. As of April 6, 2021, 37.6% of the U.S. and 45% of the lower 48 states are in drought.
