This Hazardous Weather Outlook is for portions of Puerto Rico.
.DAY ONE...Today and Tonight
.Lightning...Isolated to scattered thunderstorms, particularly
across the San Juan metropolitan area and western sections. Be
prepared to stop all outdoor activities and seek shelter if storms
develop.
.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across western sections. 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 all coastal and urban areas.
.Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly
across southwestern sections. Unsecured items could blow around.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across northern and eastern Puerto Rico
and Culebra. Isolated stronger rip currents may occur elsewhere,
especially near piers, jetties, and channels.
.DAYS TWO THROUGH SEVEN...Tuesday through Sunday
Daily afternoon thunderstorms will bring a limited to elevated
risk of flooding and lightning, mainly but not limited to western
and northern Puerto Rico. In addition, the proximity and arrival
of a frontal boundary and an associated pre-frontal trough mid-to-
later in the week will support more widespread and longer-lasting
shower and thunderstorm activity, further increasing the flood
and lightning threat. An elevated heat threat will persist through
the workweek, while a moderate rip current risk continues along
northern and eastern beaches. However, long-period northerly
swells arriving this weekend will significantly worsen marine and
coastal conditions, leading to hazardous to potentially life-
threatening surf and rip currents.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed.
