This Hazardous Weather Outlook is for portions of Puerto Rico.
.DAY ONE...Today and Tonight
.Lightning...Isolated thunderstorms, particularly across
southeastern, central, and western to northwestern Puerto Rico, as
well as portions of the San Juan metropolitan area. Stay alert
and be prepared to take shelter if storms develop.
.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across eastern Puerto Rico,
interior to northwestern Puerto Rico and downwind of El Yunque
and the local islands. 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 primarily those
individuals extremely sensitive to heat, especially when outdoors
without effective cooling and/or adequate hydration. These
conditions are most likely across western Puerto Rico.
.Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly
across coastal areas of southern and northern Puerto Rico, Vieques
and Culebra. Unsecured items could blow around.
.Marine Conditions...Small craft should exercise caution across
most of the local waters.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone of most local beaches. Isolated stronger rip currents
may occur elsewhere, especially near piers, jetties, and channels.
.DAYS TWO THROUGH SEVEN...Friday through Wednesday
Moderate to fresh winds will continue through the weekend,
bringing breezy conditions to land areas through Saturday, while
creating choppy seas for small craft through Friday and a moderate
rip current risk through Sunday. On Friday, increasing moisture
and favorable upper-level conditions will enhance shower and
thunderstorm development, raising the risk of flooding and
lightning. The most significant risk is likely on Friday and
Saturday, when peak moisture and instability are forecast. Despite
the rain, a limited excessive heat risk will persist, especially
in western Puerto Rico, particularly for those sensitive to heat
when outdoors without proper cooling or hydration.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed.
