USVI Drought Summary

During this USDM week (3/25/20-3/31/20), surface and mid- to upper-level troughs moved across the U.S. Virgin Islands (USVI), generating scattered showers, while a surface high moving across the western Atlantic created a fresh to locally strong northeasterly flow. The troughs were replaced by a dry and stable air mass associated with strong high pressure ridging both in the upper level and at the surface.

Radar-based estimates of rainfall for the 7 days ending at 12z on Tuesday depicted up to half an inch of precipitation across scattered parts of the USVI, with other parts receiving little to no precipitation.

This week was drier than normal at all reporting stations with weekly rainfall totals ranging from 0.03 inch at Windswept Beach on St. John and 0.08 inch at CoCoRaHS stations Anna’s Retreat and Christiansted 4.1 ESE, to 0.25 inch at East Hill and 0.32 inch at the UVI sheep farm, both on St. Croix. But last week was wet and month-to-date totals are still above normal. The USGS well on St. John (Susannaberg DPW 3) continued to decline this week; the well on St. Croix (Adventure 28) has started rising in the past week; and the one on St. Thomas (Grade School 3) was rising the last 2 weeks, leveled off this week, but the last two days has started decreasing again. There was no change in the USDM status from last week, with D-Nothing continuing for St. John and St. Thomas, and D0-L continuing for St. Croix.
