This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Excessive Heat...Heat index above 112 degrees across portions of
west to northwest and north-central municipalities, San Juan and
Vicinity and Culebra (heat exhaustion or heat stroke likely with
prolonged exposure). Heat index of 108-111 degrees across some of
the southeast and northeast, including Caguas and Gurabo, (heat
exhaustion or heat stroke possible). Heat index of 102-107 degrees
for portions of other coastal and urban areas of southwest Puerto
Rico and Vieques (heat exhaustion possible with prolonged
exposure).

.Wind...Breezy conditions along some of the coastal areas mainly
during the late morning and afternoon hours. Unsecured items could
blow around.

.DAYS TWO THROUGH SEVEN...Sunday through Friday
A limited to significant risk of excessive heat is expected to persist
through at least Monday afternoon. An Excessive heat Watch will therefore
remain in effect until then. Breezy conditions will persist along coastal
areas especially during the late morning and afternoon hours. Another
surge of moisture accompanying a Tropical wave is forecast to cross
the region Tuesday through Wednesday thus increasing the chance for
enhanced shower development. This may lead to ponding of water on roads
and poorly drained areas as well a minor urban flooding in isolated
spots.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
