PZZ500 838 Am Pdt Sat May 11 2024
Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
a compressed and shallow marine layer is currently hugging a majority of the coastline with some lingering fog this morning. Surface high pressure will allow for fair weather and moderate northwesterly breezes to prevail this weekend. Winds begin to increase Monday as surface high pressure over the eastern pacific ocean builds and moves east, keeping things dry with northwest winds increasing to a fresh breeze, particularly over the outer waters, north bay coast, and big sur coast. Significant wave heights will also begin building as a result at the start of next week.

SYNOPSIS
Issued at 134 AM PDT Sat May 11 2024

Warm temperatures continue inland today with highs from the upper 80s to lower 90s. Cooling has begun at the coast and spreads inland over the weekend into Monday with seasonal to warm temperatures through the next week. Areas of morning low clouds and fog are possible over the next few days.

UPDATE
Issued at 919 AM PDT Sat May 11 2024

Satellite at this hour shows largely clear skies. The one exception is Monterey Bay and portions of the Sonoma coast where dense fog is limiting visibility. However, fog is expected to begin to dissipate within the hour, lending to clear skies throughout the day today.

SHORT TERM
(Today and tonight)
Issued at 134 AM PDT Sat May 11 2024

Moisture within a very shallow marine layer has brought areas of low stratus and dense fog to coastal portions of the region early this morning. Given reduced visibility on area webcams and observations a Dense Fog Advisory was issued for areas from SF south through Monterey Bay and down the Big Sur coast. Visibility values are bouncing around somewhat in places, but prepare for sudden changes if you have travel plans overnight. The advisory will continue through 10 AM this morning. Expect fog/stratus to retreat towards the coast thereafter with the marine layer keeping coastal/bayside temperatures cool this afternoon. It will be a different story inland as readings climb well into the 80s. The warmest locations will be within the North/East/South Bay Valleys and within southern interior Monterey and San Benito Counties, where a moderate HeatRisk will exist. This means that sensitive populations should take care and practice heat safety during the warmest (late morning - early evening) daytime hours. By tonight expect stratus/fog to redevelop along coastal areas with another chance for dense fog yet again into Sunday morning. Lows will be mostly in the 50s.

Here's some safety tips for hot temperatures:

* 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.

LONG TERM
(Sunday through Friday)
Issued at 134 AM PDT Sat May 11 2024

The upper ridge will weaken with a slight cooling trend developing by early next week. Temperatures will moderate a bit for mid to late week with the trend of warmer temperatures inland and cooler temperatures along the coast continuing. In general look for highs in the 80s inland, 70s within the marine influenced valleys, and 60s on the beaches. Looking forward the latest climate outlook from the Climate Prediction Center suggests temperatures and precipitation should remain near seasonal averages between May 18th-24th.

AVIATION
(18Z TAFS)
Issued at 1032 AM PDT Sat May 11 2024

Currently VFR and a beautiful day for flying across major terminals. Thin layer of stratus and fog along the coast under a very shallow marine layer will likely remain through much of the day with some areas periodically mixing out. Typical diurnal onshore flow pattern as far as winds go this afternoon and overnight. Weak upper low passing through Sunday morning should provide some expansion of the marine layer, leading to slightly higher cigs tonight compared to last night. Though still holding high confidence in IFR cigs for North Bay and Monterey Bay terminals.

Vicinity of SFO...VFR through the daytime hours today. Moderate confidence in return of marine stratus tonight. Most lower vis and cigs likely stay confined to coastal areas and through the Golden Gate. However, weak upper low moving through should provide enough lift in the marine layer to see some stratus moving into the Bay tonight. Moderate-to-high confidence in clearing time Sunday morning. Typical diurnal onshore winds during the afternoons.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR through most of the day. Early return of IFR cigs likely this evening. Should see enough lift in the marine layer Sunday morning to have slightly less of a FG impact and cigs slightly higher around FL004-FL008. However, this is a low-to-moderate confidence scenario.

MARINE
(Today through Thursday)
Issued at 919 AM PDT Sat May 11 2024

A compressed and shallow marine layer is currently hugging a majority of the coastline with some lingering fog this morning.
Surface high pressure will allow for fair weather and moderate northwesterly breezes to prevail this weekend. Winds begin to increase Monday as surface high pressure over the Eastern Pacific Ocean builds and moves east, keeping things dry with northwest winds increasing to a fresh breeze, particularly over the outer waters, North Bay Coast, and Big Sur Coast. Significant wave heights will also begin building as a result at the start of next week.

BEACHES
Issued at 719 PM PDT Fri May 10 2024

Long period southwest swell will lead to slightly elevated chances for sneaker wave and rip current development this weekend.
Conditions are expected to stay below Beach Hazards Statement criteria as swell height will only be between 1-2 feet. However, in light of anomalously warm temperatures and increased likelihood of people traveling to the coast, visitors to the beach should remember to take safety precautions to prevent being caught by an unexpected large wave and to never turn your back on the ocean.

MTR WATCHES/WARNINGS/ADVISORIES
