This Hazardous Weather Outlook is for portions of USVI.

.DAY ONE...Today and Tonight

.Excessive Heat...This level of heat affects anyone without
effective cooling and/or adequate hydration, with those sensitive
to heat at the highest risk. Impacts likely in some health
systems, heat-sensitive industries and infrastructures. These
conditions are most likely across low, urban and coastal areas
of Saint Thomas, Saint John, and Saint Croix.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Heat threats will remain the primary concern through Monday while
the risk of flooding and lightning strikes will persist each day
(particularly during the afternoons). During the weekend we
expect the arrival of a tropical wave, which will increase the
potential for rainfall activity and instability across the islands.
Low marine and coastal risks are forecast through Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is encouraged. Please relay any information
about flooding, winds, waves, and rip currents to the National
Weather Service in San Juan.
