.SHORT TERM...
Issued at 147 PM PST Tue Nov 3 2026
(This evening through tonight)

Satellite imagery this afternoon shows an area of low pressure 
moving into our northern outer waters, just outside of 60nm and west 
of Sonoma COunty. THe main band  of rain has pushed inland with 
showers lingering behind it. More to the west, where the low is, 
cumulus clouds are forming along the cold front. Looking at the SPC 
mesoanalysis page, just next to that region it shows around 100-150 
J/kg of CAPE and some shear. The other convective parameters are not 
as favorable such as positive LI and the lapse rates becoming more 
stable. Think that these conditions will generally hold for the 
afternoon as cloud cover filled ahead of the front. An isolated 
rumble of thunder or two is possible over the waters, but generally 
the thunder chance is less than 10%. Instead, we'll likely see 
additional rainshowers activity as the front approaches. Precip 
chances taper off this evening, with dry weather expected for most 
areas by the late evening or early hours of Wednesday morning. 
Behind the front, look for clear skies tonight and near seasonal low 
temperatures.

.LONG TERM...
Issued at 147 PM PST Tue Nov 3 2026
(Wednesday through next Monday)

Wednesday, high pressure builds into the region leading to a stretch 
of warmer and drier weather. Wednesday will be the start of the 
warming trend; however, we'll still be leaning seasonable to 
seasonably cool. Thursday into the weekend, high temperatures slowly 
climb leading to temperatures becoming unseasonably warm by the 
weekend where temperatures could be 10 to 15 degrees above their 
normals. 

In addition to that, tides continue to trend on the higher end. 
Opted to issue a Coastal Flood Advisory for the San 
Francisco Bayshorelines from 6AM Wednesday through 1PM MOnday. 
Minor to moderate coastal flooding is expected during this time 
frame.

Issued at 353 PM PST Tue Nov 3 2026

.BEACHES...
Issued at 327 AM PST Tue Nov 3 2026

Hazardous beach conditions will be present at 
Pacific Coast beaches Tuesday as long period (15-19 second) 
northwesterly swell will bring an increased risk for sneaker waves 
and strong rip currents. Waves can sweep across the shoreline 
without warning, pulling people into the sea from beaches, jetties, 
and rocks. Stay off of jetties, piers, rocks, and other waterside 
infrastructure. Remain out of the water to avoid hazardous surf and 
never turn your back on the ocean! Hazardous beach conditions may 
linger into Wednesday and thus may warrant an extension of the Beach 
Hazards Statement.
