Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Locally breezy northwest winds will persist over the northern and outer waters into this evening. These winds will generate steep fresh swell resulting in hazardous seas conditions, particularly for smaller vessels. Winds will then gradually diminish into Tuesday. Light winds mid to late week before re-strengthening into the weekend as the next system moves through. The sea state continues to be dominated by wind driven northwest waves. These waves will subside into mid-week as winds ease. Additionally, a pair of light northwest and southerly swells throughout the forecast period.

Area Forecast Discussion National Weather Service San Francisco Bay Area 208 PM PDT Mon May 10 2021

SYNOPSIS. A Red Flag Warning remains in effect through 6 pm Tuesday for the North and East Bay Hills as well as the East Bay Interior Valleys. Otherwise, expect continued sunny and warm weather through Tuesday. A cooling trend begins Wednesday and lasts through the end of the week and into next weekend as the marine layer will redevelop with onshore winds returning.

DISCUSSION. As of 2:05 PM PDT Monday . Water vapor imagery continues to show a disturbance digging across the Great Basin this afternoon, with much drier air filtering into the region. In fact, the dew points across the North and East Bays are falling into the mid 20s and lower 30s at this time, running up to 8 degrees lower than yesterday. Meanwhile, the north to northeast winds remain gusty, but not as strong as we were seeing earlier today. These winds will increase once again tonight and continue through Tuesday morning, combining with poor overnight humidity recovery in the hills to maintain elevated fire danger across the region into Tuesday. See Fire Weather Discussion below for details.

PREVIOUS DISCUSSION. As of 10:00 AM PDT Monday . Water vapor imagery shows an inside slider digging across the Great Basin this morning, with a clear boundary extending from Cloverdale in Sonoma County through Winters and Elk Grove in the Central Valley to Strawberry in the Sierra. Extremely dry air is behind this boundary, with humidities values expected to fall into the single digits today across the North Bay Mountains and East Bay Hills. Meanwhile, current gusts are between 30 and 40 mph in these areas, with local gusts around 50 mph ongoing. Given these current conditions and the impending dry air intrusion, the Red Flag Warning looks on track for today. These offshore winds will also allow for some compressional heating today, so expect warmer conditions today for the North and East Bays.

Otherwise, just dealing with some low clouds along the coast from San Mateo County southward through Monterey County this morning. Visible imagery shows two nice Otter Eddies, one approaching the Monterey Peninsula and the another along the Big Sur Coast. A third appears to be trying to spin up along the Santa Cruz Coast, which are just fun to watch. The low clouds will help moderate temperatures along the immediate coast, but inland areas should still warm nicely. Current forecast looks on track, so no updates are planned at this time. Palmer

AVIATION. As of 11:49 AM PDT Monday . VFR continues across the Bay Area today. The afternoon will offer breezy northwest winds for the afternoon with 20 to 25 mph gusts possible through some of the coastal gaps. SFC winds weaken into the evening, but LLWS will become a minor concern overnight for North and East Bay terminals as winds aloft strengthen. Monterey Bay terminals will begin to see lowered ceilings overnight, falling into IFR criteria.

Vicinity of KSFO . VFR through the evening. Northwesterly winds will build into the afternoon peaking around 20 kts. Surface winds will decrease and a few low level stratus clouds will filter into the area. Skies will clear into the late morning.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR and mild winds will last through the afternoon. Coastal stratus returns in the evening and ceilings look to fall below 1000 AGL overnight. Expect IFR conditions with light winds lasting until the early morning.

FIRE WEATHER. As of 3:22 AM PDT Monday . Red Flag Warning remains in effect through 6 pm Tuesday for zones 507/510/511. Conditions are moderated at the moment but expect rapid warming and drying today as north winds filter over the region. By this afternoon inland highs into the low 90s with RH values teens and single digits inland as north winds arrive. Peak period of concern looks to be from about sunset tonight through sunrise to 10 am Tuesday. During this time northeast winds will peak with gusts generally 35-45 mph in the hills. Models indicate there will be essentially no humidity recovery overnight and in fact some places may dry as the offshore flow intensifies. The areas under the Red Flag Warning pretty much encapsulate the areas where we expect the worst combination of winds, temps, humidity and dry fuels. Will say latest model trends have backed off slightly on winds but overall pattern and state of fuels justifies the Red Flag as any nighttime ignitions would be problematic.

Winds will ease by mid morning Tuesday. Red Flag will stay in place through the hottest/driest part of the day Tuesday. This was coordinated with WFO Sacramento for a 6 pm Tuesday end time.

Onshore breezes should return by Tuesday evening with moderating conditions into Weds in terms of cooler temps, higher humidity and a general return of onshore winds.

MARINE. as of 11:46 AM PDT Monday . Moderate to locally strong northwest winds for today with gale force gusts over the northern outer waters into this afternoon. These winds will generate steep fresh swell resulting in hazardous seas conditions. Winds will then gradually diminish into tomorrow with locally breezy conditions over the northern outer waters. Lighter winds for mid- week before re-strengthening into the coming weekend as the next system moves through. Wind driven northwest waves continue to dominate the seas state along with lighter northwest and southerly swells.
