Some heavy rains on Puerto Rico allowed for improvements on the eastern side of the island, with abnormally dry and moderate drought conditions showing some improvements.

Drought persists across the U.S. Virgin Islands, although increased rainfall in St. Thomas prompted improvement to D1 there. St. Croix and St. John remain in severe drought. King Airport near Charlotte Amalie in St. Thomas has recorded a fairly-typical 6.3 inches of rain in the last 9 weeks, following a four-month period (December 2020 – March 2021) with less than 4 inches of rain. Even though these are the driest months of the year at St. Thomas, the observed totals were less than half of normal.

The first week of June brought about ¾ of an inch of rain to Rohlsen Airport near Christiansted in St. Croix, which is slightly more than normal; however, this followed 10 consecutive months with below normal rainfall. About 23 inches of rainfall has accumulated since August 2020, which is nearly a foot below normal.

Windswept Beach in St. John recorded a near-normal 0.63 inch of rainfall for the week, but of the 15 weeks since late February, just 3 were wetter. Of the past 105 days, only 4 received more than 1/4 inch of rain, and less than 7.5 inches has fallen since February 1, 2021.
