DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN JUAN PR
220 AM AST Fri Sep 10 2021
...Moderate drought conditions (D1) continue to prevail across
much of the southern coast of Puerto Rico, as well as the
northwest coast and parts of the eastern interior. Saint Croix and
Saint John are also in moderate drought (D1), while Saint Thomas
remains drought free...
SYNOPSIS...
Beneficial rains from Tropical Cyclones Fred and Grace were
observed across the local islands with some drought improvement
noticed. However, significant dryness over the islands in the 3
weeks since the passage of Tropical Cyclone Grace has again
increased short-term drought stress on agriculture and water
levels.
SUMMARY OF IMPACTS...
STATE AND LOCAL ACTIONS.
Voluntary water-use restrictions have been requested with some
water restrictions imposed in some areas. The fire danger weather
in Puerto Rico continues to increase as dryness intensifies. A
decreasing trend in water levels are observed at some reservoirs
and aquifers across Puerto Rico. Across the USVI, livestock
farmers are buying hay and have done so since March.
SOIL MOISTURE CONDITIONS.
Data retrieved from the Puerto Rico Agricultural Water Management
(PRAGWATER) continue to indicate dry soils across southern Puerto
Rico as well as a few spots across the eastern interior and the
northern coast of the island.
GROUNDWATER CONDITIONS.
The groundwater levels retrieved from the U.S. Geological Survey
(USGS) network indicated most of the representative wells along
the southern slopes and north central Puerto Rico running below or
much below the normal range. As far as the U.S. Virgin Islands,
although representative wells at Saint Thomas and Saint Croix are
running at normal levels, a decreasing trend continues to prevail.
RIVER AND STREAM FLOW CONDITIONS.
The 28-day average streamflow measured by the U.S. Geological
Survey (USGS) gaging network shows most of the streamflows across
the eastern interior and central Puerto Rico running below or much
below the normal range.
CLIMATE SUMMARY...
The 90-day rainfall deficits now range between 8 and 12 inches
across the municipalities of Patillas, Guayama, and western
Cayey, as well as parts of the east central interior. The 90-day
rainfall deficits across the U.S. Virgin Islands range from near
zero in St. Thomas to about 2-3 in St. Croix and St. John.
PRECIPITATION/TEMPERATURE OUTLOOK...
EXTENDED FORECAST.
Long term forecast continue to show an above-average probability
of above-normal tropical cyclone activity in the Atlantic Basin.
This should prevent widespread drought from taking hold of the
islands this fall, however, additional deterioration in drought
conditions is possible into late September.
NEXT ISSUANCE...
THIS PRODUCT WILL BE UPDATED BY THE END OF SEPTEMBER OR SOONER IF
NECESSARY IN RESPONSE TO SIGNIFICANT CHANGES IN CONDITIONS.
