North Bay Interior Valleys Severe Watches & Warnings NOAA Weather Radio

... Heat advisory remains in effect until 9 PM PDT this evening... 

A heat advisory remains in effect until 9 PM PDT this evening. 

* Temperatures... high temperatures are forecast to range from 90 
  to 105 degrees across most inland areas with locally hotter 
  temperatures possible. The immediate coast will mostly be 
  spared from the heat. Overnight cooling will provide some 
  relief but nighttime lows are forecast only to drop into the 
  upper 50s and 60s for most inland areas. For communities in 
  the thermal belt at higher elevations, expect warmer overnight 
  lows in the lower to mid 70s. 

* Thursday high temperature ranges: South Bay/Santa Clara 
  valley: 90-100f (locally up to 103f), San Benito 
  mountains/Pinnacles np: 95-105f (locally up to 110f). 

* Impacts... prolonged exposure to these temperatures will 
  increase the risk of heat related illnesses, particularly for 
  vulnerable populations such as the elderly or infirm. Pets and 
  livestock may also require extra care through the warm 
  weather. Individuals heading to the coast for heat relief and 
  unfamiliar with the ocean may be at increased risk of 
  hypothermia or being pulled out to sea by rip currents. Hot, 
  dry weather will increase risk of human sourced wildfire. 

Precautionary/preparedness actions... 

A heat advisory means that a period of hot temperatures is
expected. The hot weather will create a 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. Avoid leaving pets or family members in
hot cars.

for gusty north winds and low humidity for fire weather zones 
213, 215, 216, 217, 218, 263, 264, 266, and 279... 

* wind... north winds 10 to 20 mph, with locally higher gusts to
  around 30 mph, spreading southward from the from the northern
  Sacramento Valley and adjacent foothills down the valley and
  into portions of lake and Solano counties tonight and Thursday.  
  Decreasing winds late Thursday night and Friday.
 
* Humidity... poor humidity recovery tonight as low as 25-40
  percent. Minimum humidity lowering into the single digits and
  teens Thursday afternoon. Slight improvement Thursday night and
  Friday.

* Impacts... any fires that develop will likely spread rapidly. 
  Outdoor burning is not recommended.

Precautionary/preparedness actions... 

A red flag warning means that critical fire weather conditions
are either occurring now, or will shortly. A combination of
strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.
