...HEAT ADVISORY IN EFFECT FROM 10 AM THIS MORNING TO 3 PM AST THIS
AFTERNOON...

* WHAT...This level of heat affects most individuals sensitive to
  heat, especially those without effective cooling and/or adequate
  hydration.

* WHERE...All of Puerto Rico, including Vieques and Culebra, and the
  U.S. Virgin Islands.

* WHEN...From 10 AM this morning to 3 PM AST this afternoon.

* IMPACTS...High temperatures or elevated heat indices can worsen
  symptoms in people with chronic conditions. They can also increase
  the risk of heat-related illness among individuals sensitive to
  heat with inadequate cooling or hydration. These risks are highest
  across coastal areas, lowlands, interior valleys, and urban zones.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Drink plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors.

Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to early morning
or evening. Take action when you see symptoms of heat exhaustion and
heat stroke.
