Southern Puerto Rico continued to dry out and has begun to raise concerns among water suppliers. Moderate drought and abnormally dry conditions expanded this week.

Dry conditions persisted across the U.S. Virgin Islands this week, with St. John and St. Thomas degrading from abnormal dryness (D0-S) to short-term moderate drought (D1-and St. Croix remained in short-term moderate drought (D1-S). On St. John, Rafe Boulon/Windswept Beach reported no rain and CoCoRaHS stations across the island only recorded an average of 0.08 inches. Groundwater levels at the Susannaberg DPW 3 well was 15.02 feet below the land surface on June 9; analysis shows that water levels have mostly declined since October 19, 2025. Over the past year, this groundwater level has dropped approximately 5.2 feet from the 9.82 feet reported on June 9, 2025. This localized dryness is backed up by the short-term SPI.

On St. Thomas, Cyril E. King Airport also reported no rain this week and CoCoRaHS stations averaged 0.08 inches. The depth to water at the Grade School 3 well was measured at 9.03 feet below the land surface on June 9, showing a slight increase of 0.1 feet from last week (June 2 - 9.03 feet). SPI values confirm these emerging deficits, showing dry conditions at the 1-, 3- and 6-month timescales, while longer-term SPI timescales for the island were unavailable.

On St. Croix, a total of 0.06 inches of rain was reported on St. Croix at Henry Rohlsen Airport this week, while the East Hill station recorded 0.71 inches this week (matching the average CoCoRaHS observations of 0.72 inches). The depth to water at the Adventure 28 Well was 21.76 feet below the land surface on June 9, reflecting a steady and severe decrease over the past year. This is a drop of 7.6 feet compared to this time last year, when the groundwater level sat at 14.46 feet on June 9, 2025. Reflecting this prolonged deficit, the 1-, 3-, 6-, 9- and 12-month SPI values all confirm prevailing dry conditions on St. Croix.
