GOES-West visible imagery shows clear skies across most of the area with lingering stratus hugging close to the Pacific coastal communities and western San Francisco. The stratus will continue to recede to the marine environment this afternoon but will return overnight.
Upper-level pattern continues to be dominated by ridging over the eastern Pacific. While a few degrees cooler than yesterday, ridging will keep afternoon high temperatures warmer than usual, particularly for interior areas. High temperatures will be in the 80s to near 100 degrees for far inland locations leading to localized Moderate HeatRisk, especially noted in the Santa Clara Valley and Alameda and Contra Costa counties. The Heat Advisory will end at 7 PM PDT this evening however precautions should continue to be taken to alleviate the risk for heat related illnesses Sunday through Tuesday. Ways to stay safe during the heat is to wear light weight, loose clothing, drink water frequently, and spend time in the shade or in air conditioned buildings. Know the difference between heat exhaustion and heat stroke, keeping in mind that heat stroke is a medical emergency.
High tide flooding will continue to occur nightly along the low- lying areas of the Bayshore and the Pacific Coast through the middle of next week. The combination of an upcoming new moon and lunar perigee on Sunday, about 7 inches of additional tidal anomaly from a combination of storm surge, thermal expansion of the Eastern Pacific, and about 2 inches inches of Sea Level Rise since the vertical datums were established in the 80s and 90s will add up to bring tides up to 2.0 feet above normal through early next week. While lower than the historic tidal flooding in January (peaked at 2.6 ft) the tides this weekend could end up being the highest observed in the Summer, beating the current record of 1.7 ft from July 2022.

Starting tomorrow, the high pressure situated over the Pacific will flatten and begin to weaken slightly, allowing for daytime temperatures to gradually cool and return to mid-June climatological normal. Usual June stratus along the Pacific Coast is expected for the next several days.

Stratus and fog impacted the coastal and Bay Area terminals this morning. Daytime heating has allowed for that to burn off with the marine layer retreating as well. Some of the inland terminals also were impacted, such as KSTS, KAPC, and KSNS. VFR conditions will continue through the afternoon and into the evening hours before the marine layer pushes back inland bringing stratus and fog back to the region. High resolution modeling continues to show coastal stratus and fog (IFR-LIFR) to redevelop tonight and tomorrow morning. Similar conditions from this morning are expected again tomorrow morning. Winds will follow similar patterns to the past 24 hours with speeds increasing to moderately breezy this afternoon, but diminishing around sunset.
Vicinity of SFO, Similar conditions from the past 24 hours are expected for the next 24 hours. High confidence of VFR conditions continuing into the overnight hours. Current NE winds will go NW'rly early this afternoon (~20Z). Wind speeds will increase into the middle teens this afternoon, but subside back below 10 kt around or shortly after sunset. Winds will then go westerly early tomorrow morning before going N/NE by the middle of tomorrow morning. Radiative cooling may result in some additional areas of patchy low stratus/fog developing during the overnight/morning hours tomorrow.
SFO Bridge Approach, Similar to SFO.
Vicinity of SJC and OAK, Similar conditions from the past 24 hours are expected for the next 24 hours. Winds will predominately be out of the W/NW at OAK through the period. Winds at SJC will be out of the NW through this evening before going S/SE during the overnight hours. Wind speeds, at both sites, will be in the low to mid teens this afternoon through sunset, otherwise winds will be aob 8 kt. For OAK, morning stratus/fog (IFR) is expected to redevelop tonight and tomorrow morning, otherwise VFR conditions are expected. At SJC, stratus is expected to start impacting the terminal during the overnight hours (starting ~09Z), however CIGs are not expected to develop with this stratus over the terminal and VIS is not expected to decrease.
Monterey Bay Terminals, Similar conditions from the past 24 hours are expected for the next 24 hours. Stratus/fog from earlier this morning has burned off with diurnal surface heating allowing for conditions to improve to MVFR-VFR. Stratus/fog (IFR/LIFR) is expected to redevelop and move inland tonight and tomorrow morning. The stratus and fog is expected to start to impact the Monterey Bay terminals as early as 03Z. Winds will be light and variable (but will tend to be more onshore winds) through the majority of the period. W/NW winds are expected to increase to 7-13 kt this afternoon, then subside around sunset.

A gentle southerly breeze and moderate to rough seas with a low south southwest swell persist across most of the coastal waters. Fresh to strong breezes will be possible along the Big Sur coast through this evening. Winds will remain fairly consistent through the weekend as the seas subside.

Long period southerly swell will continue through the weekend, especially for south and southwest facing beaches. Hazardous beach conditions are advertised, specifically for moderate to steeply sloped beaches along the Pacific Coast of the North Bay, San Mateo, Santa Cruz counties. A Beach Hazards Statement is in effect for Pacific coast beaches along the central coast and the Bay Area coast from late tonight through late Tuesday night. Be sure check beach conditions before you head out. Sneaker waves will run up the beach much farther than other waves, potentially catching beachgoers by surprise and resulting in people being swept into the water. Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean!
Ca, Coastal Flood Advisory until 3 AM PDT Wednesday for CAZ006-506- 508.
Beach Hazards Statement from late tonight through late Tuesday night for CAZ006-505-509-529-530.
Coastal Flood Advisory from 7 PM this evening to 3 AM PDT Tuesday for CAZ505-509-529-530.
Heat Advisory until 7 PM PDT this evening for CAZ510-513>515.
PZ, Small Craft Advisory until 9 PM PDT this evening for Pt Pinos to Pt Piedras Blancas 0-10 nm.
