The heat wave forecast for the Labor Day weekend just got longer.
The National Weather Service extended its excessive heat watch another day, so it will be in effect from 11 a.m. Saturday to 8 p.m. Tuesday.
And it now covers the entire Bay Area.
Temperatures will begin climbing Wednesday at least a few degrees in most areas, reaching the low 90s in the East Bay's interior.
For the holiday weekend, temperatures are expected to reach the 80s on the coast, the mid 80s to low 90s around the bay and the 100s in most inland areas.
Forecasters urge the public to take the following precautions beginning Thursday:
- Avoid being outdoors during the day.
- Stay hydrated and in a cool place.
- Use air conditioning if available.
- Cancel outdoor activities during the hottest period of the day.
Meanwhile, Cal ISO says it is anticipates issuing flex alerts during the heat wave as people try to stay cool, but nothing official had been announced as of Wednesday morning.
