This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms, particularly across
interior and western/northwestern sections, also likely over the San
Juan Metropolitan Area. Stay alert and be prepared to take shelter
if storms develop.

.Excessive Rainfall...Ponding of water in roads and poorly
drained areas, particularly across the northwestern section. There
is a low chance of localized urban and small streams flooding.

.Excessive Heat...This level of heat affects primarily those
individuals extremely sensitive to heat, especially when outdoors
without effective cooling and/or adequate hydration. These
conditions are most likely across urban and coastal areas.

.Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly
across coastal areas. Unsecured items could blow around.

.Marine Conditions...Small craft should exercise caution,
particularly across offshore Atlantic and Caribbean waters,
including local passages.

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

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

The heat risk will increase and remain elevated for the next
several days. Tropical waves approaching the region will increase
the flooding risk on Thursday and Sunday, increasing chances of
urban and small streams flooding. Increasing winds will bring
breezy to locally windy conditions across the coastal areas.
Additionally, choppy seas are likely to create hazardous
conditions for small craft by Wednesday and Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
