CARIBBEAN DROUGHT BULLETIN From Caribbean Drought & Precipitation Monitoring Network (CDPMN)

Announcement

With most of the Caribbean receiving normal to above
rainfall totals over the second half of the 2020 wet
season, there are no concerns over short term
drought that can affect streams, rivers and ponds by
the end of March 2021. However, some concerns exist
over long term drought that can impact large rivers,
reservoirs, and groundwater by the end of May 2021.
This is particularly so for southern Belize and French
Guiana, and in the vicinity of Antigua where water
resources should be closely monitored. The Cayman
Islands and St. Kitts/Nevis should also monitor water
resources as a precaution against long term drought.
