This Hazardous Weather Outlook is for portions of Puerto Rico.
.DAY ONE...Today and Tonight
.Lightning...Isolated thunderstorms, particularly across
west to northwest PR. Stay alert and be prepared to take shelter
if storms develop.
.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across west to northwest PR.
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 coastal and urban areas.
.Wind...Breezy conditions (18-22 kts | 21-25 mph). Unsecured
items could blow around.
.Marine Conditions...Small craft should exercise caution across
most local waters.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across northern, eastern and southeastern
PR, including Vieques and Culebra. Isolated stronger rip currents
may occur elsewhere, especially near piers, jetties, and
channels.
.DAYS TWO THROUGH SEVEN...Sunday through Friday
A tropical wave will approach from the eastern Caribbean later
tonight into Sunday, increasing the risk of flooding and
lightning. An area with slightly drier air and suspended Saharan
dust particles will follow Sunday`s tropical wave, creating hazy
skies and deteriorating air quality. Winds and choppy seas will
continue to promote life- threatening rip currents across exposed
beaches. Limited localized flooding and lightning risk, along
with a moderate rip current risk, limited to possibly elevated
heat risk and limited marine and wind risks will persist through
most of the week. Late Thursday into Friday, the approach of a
mid- to upper- level trough/low and a tropical wave could increase
flooding and lightning risks.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed.
