Watches & Warnings

Heat Advisory
Issued: 3:38 AM PDT Jun. 22, 2017 – National Weather Service

... 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.





Fire Weather Warning
Issued: 3:12 PM PDT Jun. 21, 2017 – National Weather Service

... Red flag warning remains in effect until 11 PM PDT Thursday
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.
