This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms. Stay alert and be prepared
to take shelter if storms develop.

.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across north central and
northwestern Puerto Rico. 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 northern, western and southern
coasts of Puerto Rico.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Primary concerns through the period will focus on localized
excessive rainfall and lightning. Above-normal temperatures will
persist, with an elevated heat risk mainly Tuesday and Wednesday
across urban and coastal areas, then limited heat risk will likely
prevail the rest of the week. As trade winds strengthen, expect a
return of moderate rip current risk by next weekend.

.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.
