.SHORT TERM...
Issued at 156 PM PST Mon Feb 2 2026
(This evening through Tuesday)

The threat for minor coastal flooding is winding down as high tide
has come and now past. The only other threat from the previous AD
update is that the Beach Hazards Statement remains in effect for
Pacific Beaches through this evening. Otherwise, quiet and dry
weather continues through the short term thanks to high pressure
building over the region. Temperatures tonight will be similar to
last night or perhaps a few degrees warmer. Given the building high
pressure system, tomorrow`s high temperatures will be warmer,
putting most areas above their normal seasonal highs by 5 to 15
degrees.

.LONG TERM...
Issued at 156 PM PST Mon Feb 2 2026
(Tuesday night through next Sunday)

High pressure dominates the forecast through much of the work week,
leading to a warming and drying trend through Wednesday. Cluster
analysis shows an upper level trough developing off the California
Coast Thursday into Friday, though there is some uncertainty as to
where exactly it`ll be placed. This could spread some moisture in
from the south for us, likely leading to an increase cloud cover and
slightly cooler temperatures. The airmass should remain dry enough
to keep any showers at bay, but this will be something to watch for.

Friday into the weekend, the aforementioned low looks to be over
southern California by Saturday, with ridging setting up over the
PacNW. The forecast continues to trend dry for most of Saturday,
with chances for precipitation potentially arriving as early as late
Saturday night for areas in the far North Bay. Should the clusters
pan out, high pressure meanders eastward as a disturbance advances
towards the PacNW Sunday into Monday. Chances for rain have bumped
up with the latest forecast package, to about 30-40% for the North
Bay region and the San Francisco peninsula coast. Interior areas,
like South and East Bay are closer to the 30-35% range and for the
Central Coast chances are lower about 15-35%. What does that mean?
Regardless of rain chances, expect cooler conditions to prevail with
the return of onshore winds, and some cloud cover. Rainfall amounts
at this time remain light, with perhaps some areas seeing vicinity
showers on Sunday.

.AVIATION...
(18Z TAFS)
Issued at 920 AM PST Mon Feb 2 2026

VFR conditions will continue to prevail at all taf sites today and
through most of the night, with relatively light and variable
winds, with high confidence. However, confidence is more moderate,
as there is the potential for some fog formation again tonight,
especially for STS, which would result in sub-VFR conditions.

Vicinity of SFO...VFR conditions with light southerly flow will
continue to prevail. High confidence in VFR through the TAF
period. Diurnal winds will prevail today, with offshore flow
returning tomorrow.

SFO Bridge Approach...Similar as SFO.

Monterey Bay Terminals...Currently VFR with drainage winds at
both terminals. High confidence in VFR through the TAF period.
Diurnal winds will prevail.

.MARINE...
(Today through Saturday)
Issued at 815 AM PST Mon Feb 2 2026

Hazardous conditions will continue today for the inner waters and
outer waters due to rough seas and fresh to strong northerly
breezes. Conditions improve tomorrow as moderate seas and a gentle
northeasterly breeze prevails through Thursday. By Friday, seas
build to become rough, and northwesterly breezes increase to
become moderate once again.

&&

.BEACHES...
Issued at 257 AM PST Mon Feb 2 2026

Hazardous beach conditions will continue through this evening at
Pacific Coast beaches. Long period westerly swell will bring an
increased risk for sneaker waves and strong rip currents with
breaking waves of 14 to 19 feet. Remember: stay off of jetties,
piers, rocks, and other waterside infrastructure, remain out of
the water, and never turn your back on the ocean!
