This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms, particularly across
the northern, interior and western sectors. Stay alert and be
prepared to take shelter if storms develop.

.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across northern, interior and
western sectors. 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 most individuals
sensitive to heat, especially those without effective cooling
and/or adequate hydration. Those extremely sensitive to heat face
the highest risk. Some health systems and heat-sensitive
industries could be affected. These conditions are most likely
across urban and coastal areas.

.Marine Conditions...Hazardous conditions for small craft in
areas with seas of 7 feet or higher, particularly across the
eastern offshore Atlantic waters and Anegada Passage.

.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across northern, eastern, and southeastern
beaches, also Vieques and Culebra. Isolated stronger rip currents
may occur elsewhere, especially near piers, jetties, and
channels.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Limited to elevated flooding risk is forecast during the next few
days. The National Hurricane Center (NHC) continues monitoring
Tropical Storm Jerry. This system is expected to move northeast of
our area by Friday as a Hurricane. Hazardous marine and coastal
conditions are forecast to return tonight through Saturday. Heat
risks will also possibly continue as Jerry promotes southerly flow
through at least early Sunday. Residents and visitors should
remain informed and monitor official updates from the National
Hurricane Center and our local office.

.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.
