Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
surface high pressure over the eastern pacific ocean will build and move east, allowing for strong northwesterly breezes to prevail today and tomorrow with gale force gusts possible over the outer waters and the northern coastal zones this afternoon and evening. As this surface high pressure traverses to the north Thursday, the pressure gradient will be allowed to relax and northwesterly breezes will be allowed to diminish. By the weekend, another surface high pressure over the eastern pacific ocean builds and moves to the northeast, tightening the pressure gradient, allowing for strong northwesterly breezes to prevail over the northernmost zones. Significant wave heights build to 12 to 14 feet by Wednesday with an abating trend set for Thursday through Saturday before significant wave heights build again towards the end of the period.

SYNOPSIS
Issued at 230 AM PDT Tue Jun 4 2024

Warm to hot inland, coolest at the immediate coast today. A Heat Advisory is in effect for inland areas today through Thursday.
Temperatures will moderate towards the latter part of the week.

SHORT TERM
(Today and tonight)
Issued at 247 AM PDT Tue Jun 4 2024

Sky condition is clear (allowing improved radiative cooling vs cloud cover 24 hours ago) except for few-scattered thin high clouds and patchy morning mist or fog along the immediate coastline within a marine layer varying from a few to several hundred feet deep North Bay to 1600 feet deep over the north Central Coast.

The advertised Heat Advisory goes into effect today for the North Bay and the East Bay (the advisory expanding to include areas of the South Bay, interior Monterey county including the southern Salinas Valley and San Benito county Wednesday-Thursday).

Here are some heat safety tips:

* Stay hydrated and drink plenty of fluids.
* Wear lightweight, light-colored clothing.
* Reduce time spent outdoors or stay in the shade.
* Never leave people or pets unattended in vehicles.
* Use sunscreen if going to the coast or the pool.

Highs today will be mainly above to well above early June normal high temperatures. Highs will be coolest along the immediate coastline/beaches with 70s to a few warmer spots not far from the beaches in the lower 80s, bayside highs will be 80 to 90 with lower 90s just away from the SF Bay. Farthest inland highs today in the 90s to near 100 degrees far northern Napa county, easternmost Contra Costa county and far southern Monterey county.
The Santa Rosa coop station may near the June 4th record high 98F in 1949.

LONG TERM
(Wednesday through Monday)
Issued at 247 AM PDT Tue Jun 4 2024

As mentioned, the heat advisory continues inland areas Wednesday and Thursday. Warm to hot daytime highs, above to well above June normal highs - hottest inland with 90s to lower 100s, nearer the coast 80s and 90s, and 70s/80 at the beaches. Hot weather will result in elevated fire weather conditions at least through Thursday. Improving chances of patchy night and morning coastal stratus and fog redeveloping later in the week. The NAM forecasts the SFO-SAC pressure gradient (westerly winds) prevailing Thursday afternoon and evening, however it still make take an extra day or two for the afternoon sea breeze to bring some relief farther inland.

A high pressure system is forecast to remain nearly stationary over the west late this week into next week, surrounded by low pressure systems of various strength. Weak upper level troughing may reach California over the weekend, the daily sea breeze likely during then bringing relief at least partially inland each afternoon and evening.

AVIATION
(18Z TAFS)
Issued at 1042 AM PDT Tue Jun 4 2024

Currently VFR at all terminals with not a cloud in the sky. High confidence in VFR through the TAF period at all terminals except the Monterey Bay terminals of MRY and SNS. Winds will remain onshore through the TAF period, becoming gusty this afternoon.

Vicinity of SFO...Currently VFR with offshore flow. High confidence in VFR through the TAF period. Winds will transition to become westerly and gusty this afternoon with gusts up to 30 knots to be expected. Winds will diminish overnight and remain westerly through the TAF period.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with northwesterly flow at both terminals. Winds will prevail out of the west/northwest through the TAF period. Confidence is not high on if the terminals will see any reduction in flight category through the TAF period; however, with the pattern being dominated by high pressure, the most likely outcome would be LIFR conditions in the early-to-mid morning hours with greater confidence of occurrence at MRY as compared to SNS.

MARINE
(Today through Sunday)
Issued at 1042 AM PDT Tue Jun 4 2024

Surface high pressure over the Eastern Pacific Ocean will build and move east, allowing for strong northwesterly breezes to prevail today and tomorrow with gale force gusts possible over the outer waters and the northern coastal zones this afternoon and evening. As this surface high pressure traverses to the north Thursday, the pressure gradient will be allowed to relax and northwesterly breezes will be allowed to diminish. By the weekend, another surface high pressure over the Eastern Pacific Ocean builds and moves to the northeast, tightening the pressure gradient, allowing for strong northwesterly breezes to prevail over the northernmost zones. Significant wave heights build to 12 to 14 feet by Wednesday with an abating trend set for Thursday through Saturday before significant wave heights build again towards the end of the period.

BEACHES
Issued at 859 PM PDT Mon Jun 3 2024

A Beach Hazards Statement is in effect from Wednesday morning through Thursday evening.

A moderate-rough NW swell will arrive Wednesday and create large breaking waves and an increased risk for sneaker waves. Breaking waves will reach as high as 15-20 ft, especially along steep beaches. Sneaker waves can run over 100 ft up a dry beach, pulling people in the water from rocks, jetties, and beaches. Inexperienced swimmers should stay out of the water. Observe the ocean for 20 minutes before relaxing on the beach. The hot weather inland will lead to more people visiting the beach this week. Know where lifeguards are, obey their instructions, and never turn your back on the ocean!
