This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms, particularly across western
to northwestern Puerto Rico, as well as downwind of El Yunque, in
the afternoon. Stay alert and be prepared to take shelter if
storms develop.

.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across western to northwestern
Puerto Rico, as well as downwind of El Yunque, in the afternoon.
There is a low chance of isolated flash floods. Elsewhere, plan
for water ponding on roads and in poorly drained areas.

.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 all coastal and urban areas of
Puerto Rico.

.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across the northern exposed beaches of
Puerto Rico and Culebra. Isolated stronger rip currents may occur
elsewhere, especially near piers, jetties, and channels.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Excessive heat will remain the primary concern throughout the
period, while the risk of localized flooding and lightning
strikes will persist each day (particularly during the
afternoons). Heat risks can be up to elevated and significant. Low
marine and coastal risks are forecast.


.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
