Watches & Warnings

Excessive Heat Watch
Issued: 1:37 PM PDT Oct. 19, 2017 – National Weather Service

... Excessive heat watch in effect from Monday morning through
Tuesday evening...

The National Weather Service in San Diego has issued an excessive
heat watch... which is in effect from Monday morning through
Tuesday evening.

* Temperature... daytime maximums between 98 and 106. Nighttime minimums
in some windier locations could remain in the 70s.

* Impacts... heat related illness is likely for those involved in
strenuous outdoor activity, or those with health conditions that
do not have adequate access to air conditioning. If untreated,
heat illness events could be fatal. Never leave children or pets
inside a parked car!

* Outlook... gradual cooling will likely occur Wednesday and
Thursday.

Precautionary/preparedness actions...

An excessive heat watch means that a prolonged period of very high
temperatures is expected. The very hot weather will create a
dangerous situation in which heat illnesses are possible. Drink
plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors.
