URGENT - FIRE WEATHER MESSAGE
National Weather Service San Francisco CA
631 PM PDT Tue Jul 2 2024

...CRITICAL FIRE WEATHER CONDITIONS NOW INTO FRIDAY...

.Red Flag Warnings currently in effect for high elevations of the
North Bay, East Bay Hills, and the Santa Cruz Mtns have been
extended to 5 AM Friday. This decision was made due to a
combination of continued low RH in the teens, very dry fuels, and
the 4th of July holiday. Also, gusts of 30 to 40 mph will be 
possible across ridgetops and higher peaks. Fuels are quickly 
curing and will see no relief through this weekend. In fact, 10 
and 100 hour fuels are near historic levels in the North Bay in 
regard to the energy release component going into the weekend. The
same fuels in the Diablo Range and Santa Cruz Mtns aren't far 
behind. Further south, things start to dry out more this weekend. 
A Fire Weather Watch is in effect for the Santa Lucia Range,

359 AM PDT Wed Jul 3 2024

...CRITICAL FIRE WEATHER CONDITIONS INTO FRIDAY...

.Red Flag Warnings currently in effect for high elevations of the
North Bay, East Bay Hills, and the Santa Cruz Mtns through 5 AM 
Friday. While the winds are marginal, this decision was made due 
to a combination of continued low RH in the teens, very dry fuels,
and the 4th of July holiday. Also, gusts up to 35 mph will be 
possible across ridgetops and higher peaks. Fuels are quickly 
curing and will see no relief through this weekend. In fact, 10 
and 100 hour fuels are near historic levels in the North Bay in 
regard to the energy release component going into the weekend. The
same fuels in the Diablo Range and Santa Cruz Mtns aren't far 
behind. Further south, things start to dry out more this weekend. 
A Fire Weather Watch is in effect for the Santa Lucia Range, 
Interior Monterey and San Benito county, and the Southern Salinas 
Valley from Friday morning to Sunday night.

...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 1235 PM PDT Sun Jun 30 2024

Significant warm up still on the way for next week after near normal
temperatures this weekend. Increased fire danger next week as well
with temperatures well above normal and dry conditions through next
weekend.

&&

.SHORT TERM...
(This evening through Monday)
Issued at 1235 PM PDT Sun Jun 30 2024

A gorgeously warm day across the region today, and a great day to
be outside. Temps warm up a few degrees going into Monday as a
weak upper level trough degrades and moves inland. Highs Monday
look to be in the 90s across the interior, 80s for much of the Bay
shoreline, and 70s along coastal areas. If you live in the
interior, now is the time for any outdoor chores you may need to
get done before the warm up begins on Monday.

&&

.LONG TERM...
(Tuesday through next Saturday)
Issued at 1235 PM PDT Sun Jun 30 2024

Significant warmup really begins Tuesday as the very strong ridge
settles in across the West Coast. Not much change in the forecast
through the middle part of the week. Excessive Heat Warning goes
into effect Tuesday morning for interior areas, while lower
elevation locations that were once in the Watch have been
converted to a Heat Advisory given that they will cool off a
little more efficiently at night. Inland and high elevation areas
in the Warning will not see as much overnight relief through the
end of the week. Compressional heating under the ridge will warm
the airmass to near daily record territory above what little will
be left (if anything at all) of the marine layer. Guidance
continues to advertise 850 mb temps around 28 C, peaking
Wednesday. The daily max moving average this time of year is about
26.7 C, and we will be well above the 90th percentile, which is
about 23 C. Did nudge high and low temperatures up by a couple of
degrees Wednesday into the weekend as of this afternoon forecast
package. Far inland areas may actually end up with triple digits
into the weekend and the start of the next week. Left the timing
of the heat hazards as is for now (expiring Friday night), but
will definitely need to look into extending the Excessive Heat
Warning through the weekend. Cluster analysis still shows rather
high uncertainty regarding the breakdown of the ridge into next
week, hence the decision to wait on extending the hazards until
we become more confident over the next couple of days.

HEAT SAFETY AND IMPACTS:

By now you’re well aware that it is going to be extremely hot next
week with well-above normal temperatures; now lets talk about the
impacts of excessive heat and actions we can take to minimize those
impacts: With extreme heat, and especially prolonged heat events, it
is a marathon, and not a sprint. Our bodies, infrastructure, pets,
and livestock will be under duress from heat over the span of days
as opposed to just a day or two. Given that there is little
overnight relief expected throughout this event, this is where it
really becomes a marathon, and precautionary measures are
necessitated in order to prevent adverse results such as heat
exhaustion and stroke. This is not just for individuals sensitive to
heat, but rather, the entire population. Heat for this duration and
at these temperatures can be dangerous for everyone. Do your body a
favor and if you can, suspend outdoors activities between the hours
of 10am and 7pm on days where Excessive Heat Watches or Warnings are
in effect. Remain in air conditioning if you have that available to
you in your residence, or seek out air conditioned environments such
as stores, movie theaters, restaurants, libraries, and cooling
shelters.

If you cannot access air conditioned environments, must be outside,
work outdoors, or otherwise, there are other precautionary measures
you can take to keep yourself and your loved ones safe (including
pets!) during excessive heat. Take frequent breaks in the shade and
ensure that you are drinking plenty of cool water, or other
hydrating beverages such as sports drinks with electrolytes. Avoid
DEHYDRATING drinks such as alcohol or caffeinated beverages. That
aside, visiting your city public pool or a lake, river, or ocean
can also help keep you cool, but don’t forget the life jacket! If
planning on swimming, stick to where there is a lifeguard, and
know the ocean or river conditions before you get in. Although
outside of our area, its worth repeating: rivers can run fast and
cold with snowmelt in the Sierra Nevada mountains, and cold water
shock can set in quickly, which can lead to loss of muscle
control, and ultimately, drowning. Cold water shock can also set
in for ocean- goers. Have fun at the water, but be smart, be safe,
and Know Before You Go!

Finally, if you do not have air conditioning or cannot access it,
and also cannot access a body of water to stay cool: consider taking
cold showers or baths, turn on those sprinklers or garden hose and
have a fun time in your own makeshift “water park,” or lay a damp,
cool towel across your head or body. Even just dipping your hands
and feet in cool water can help to abate feelings of excessive heat.
For pets and livestock, make sure they have access to shade
structures or areas, and have clean water freely available to them
at all times. They do not have the same resources or ability to
notify of feeling heat-stressed as we do, so check in on them! If
they’re permanently outdoors, consider giving them a quick rinse-
down with the hose or set up misters, as the evaporation will help
to keep them cool as well.

.AVIATION...
(00Z TAFS)
Issued at 504 PM PDT Sun Jun 30 2024

VFR through the TAF period with the exception of MRY and SNS.
Incoming high pressure has kept the marine layer fairly compressed
which should keep any stratus that does develop close to the
shoreline. The NBM leaned towards stratus filtering into portions of
the Bay Area but, given how compressed/shallow the marine layer
current is, that scenario is incredibly low confidence. Gusty W to
NW winds continue through the evening before weakening overnight.
Breezy to at times gusty W/NW winds are expected to return tomorrow
afternoon.

Vicinity of SFO...VFR through the TAF period. Gusty west to slightly
west-northwest winds continue into the evening before weakening
during the early morning. Gusts greater than 35 knots are expected
to continue until 04Z with gusts dropping down to 25 knots after.
Winds weaken significantly by the early morning before gusty
conditions return by late morning.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR becoming LIFR overnight. A highly
compressed marine layer will keep stratus confined to the Monterey
Bay with impacts expected at MRY and SNS. Current Fort Ord wind
profiler data shows the top of the marine layer around 600 feet with
incoming high pressure expected to compress it further. Model
consensus increased that CIGs will develop for MRY and SNS tonight
but confidence still remains higher for MRY than SNS. Any CIGs that
do develop are expected to be fairly close to the surface (given the
shallow nature of the marine layer) resulting in IFR to LIFR CIGs
and potential visibility impacts tonight. Gusty W/NW winds up to 20
knots continue through the evening before lighter, more variable
winds return overnight. Gusty conditions are likely to return again
tomorrow at SNS with gusts up to 20 knots currently expected.

&&

.MARINE...
(Tonight through next Saturday)
Issued at 504 PM PDT Sun Jun 30 2024

  Strong northwesterly breezes with occasional gale force gusts
continues through the mid-week. As high pressure builds on
Monday, winds will become more northerly and widespread near-gale
force gusts will develop and spread across the waters.
Significant wave heights build to 10-12 feet generally through
mid-week before beginning to abate. Some potential for higher wave
heights between 12-16 feet remains possible over portions of the
northern outer coastal waters.

&&

.FIRE WEATHER...
Issued at 344 PM PDT Sun Jun 30 2024

...Critically low relative humidity expected across the interior
and in higher terrain this upcoming week, especially Tuesday and
Wednesday...

An Excessive Heat Warning is in place for most of our interior
locations, with a Heat Advisory for some locations closer to the
shoreline that may still see minimal influence of the Marine
Boundary Layer. Minimum RH values inland for the upcoming week and
beyond will mostly be in the teens, with some single digit values
in areas of higher elevation. Overnight RH recover will be poor to
non-existent as the heat wave persists through the week, and
potentially into next weekend. The hot and dry conditions continue
to move ERCs into the 70-80 percent range. With the long holiday
weekend, and the many outdoor activities expected, people need to
be careful with any campfires, and fireworks should not be used.
Any wildfire that ignites will have the potential for rapid
spread. Lightning is the only natural ignition for wildfires and
there are no thunderstorms in the forecast.
