.DAY ONE...Today and Tonight
.Lightning...Isolated thunderstorms over Puerto Rico. Stay alert
and be prepared to take shelter if storms develop.

streams, and washes, particularly across western PR. There is a
low chance of isolated flash floods. Elsewhere, plan for water
ponding on roads and in poorly drained areas.

individuals extremely sensitive to heat, especially when outdoors
without effective cooling and/or adequate hydration.
.Wind...Breezy conditions (18-22 kts | 21-25 mph). Unsecured
items could blow around.
.Marine Conditions...Small craft should exercise caution,
particularly across Caribbean and Atlantic waters.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across northern, eastern, southeastern
PR, Vieques, and Culebra. Isolated stronger rip currents may
occur elsewhere, especially near piers, jetties, and channels.
.DAYS TWO THROUGH SEVEN...Monday through Saturday
A limited flooding threat is expected for Monday. Weather
conditions should improve from Monday onward. Limited heat threat
is forecast for all the coastal areas during the period,
especially in the early afternoon hours due to the east-
southeasterly wind flow. The moderate risk of rip current will
persist through Friday.
.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.
