513 FXUS66 KMTR 021106 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 306 AM PST Mon Feb 2 2026 ...New AVIATION, MARINE, BEACHES... .KEY MESSAGES... Updated at 206 AM PST Sun Feb 2 2026 - Above normal temperatures and dry conditions through the week - Minor coastal flooding today during high astronomical tide for bayshore locations along the San Pablo Bay - Hazardous beach conditions through this evening at Pacific Coast beaches && .SHORT TERM... Issued at 159 AM PST Mon Feb 2 2026 (Today and tonight) An upper level ridge will build overhead today, bringing continued dry conditions and above normal temperatures. Clear skies aloft and light winds this morning and again late tonight will allow patchy fog to develop primarily in the North and East Bay valleys, with a lower (but non-zero) potential for fog along the coast and SF Bay shoreline. Motorists that encounter fog (locally dense) should slow down, use low-beam headlights, and leave plenty of distance ahead of them. Low temperatures will be near normal, mainly in the 40s, but some interior valleys will dip into the upper 30s. Highs today will be similar or slightly warmer than yesterday as light onshore winds keep warming in check, with temperatures up to 5 degrees above normal along the coast and 5-10 degrees above normal inland. While impacts from minor coastal flooding will be lower than previous days, high astronomical tide late this morning into early this afternoon will still bring minor flooding to bayshore locations along the San Pablo Bay in the North Bay. Hazardous beach conditions continue at Pacific Coast beaches through this evening, read more in the BEACHES section. && .LONG TERM... Issued at 159 AM PST Mon Feb 2 2026 (Tuesday through Sunday) Tuesday through Thursday, winds will turn more offshore as the ridge strengthens and slowly shifts to the northeast. This will boost highs by 4-8 degrees from today, with Wednesday expected to be the warmest day. This will translate to highs in the 70s to around 80 in interior valleys, and mid 60s to lower 70s near the coast. On Friday, the ridge will shift east as a weak trough (or even a closed low in some models) moves near the coast. For now, rain chances from this feature are very low (less than 10%), but a more favorable track of this system could increase chances of light rain. Temperatures are expected to cool a few more degrees with winds shifting more onshore during the afternoon. The pattern is finally expected to change more significantly Saturday into early next week as upper level troughing becomes more prominent along the West Coast. The trough will bring precipitation to the Pacific Northwest by Saturday, with rain chances extending south into northern and then central California by Sunday and Monday as the trough deepens and progresses to the east, accompanied by a cold front. However, rain amounts at this time appear to be light and not very impactful, with a continued cooling trend. That said, confidence is fairly high on the overall change to upper level troughing along the coast (85-90% chance of occurrence), with larger uncertainty on timing and strength of the trough. && .AVIATION... (12Z TAFS) Issued at 257 AM PST Mon Feb 2 2026 Currently VFR at all terminals. Patches of fog/stratus have been observed intermittently overnight - expect this to continue through mid-morning. High confidence in VFR prevailing through the TAF period by this afternoon with moderate confidence on sub-VFR conditions returning to STS tonight. Diurnal winds will prevail. Vicinity of SFO...Currently VFR with light southerly flow. High confidence in VFR through the TAF period. Diurnal winds will prevail today, offshore flow returns tomorrow. SFO Bridge Approach...Similar as SFO. Monterey Bay Terminals...Currently VFR with drainage winds at both terminals. High confidence in VFR through the TAF period. Diurnal winds will prevail. && .MARINE... (Today through Saturday) Issued at 257 AM PST Mon Feb 2 2026 Hazardous conditions are expected today for the inner waters and outer waters due to rough seas and fresh to strong northerly breezes. Conditions improve tomorrow as moderate seas and a gentle northeasterly breeze prevails through Thursday. By Friday, seas build to become rough and northwesterly breezes increase to become moderate. && .BEACHES... Issued at 257 AM PST Mon Feb 2 2026 Hazardous beach conditions will continue through this evening at Pacific Coast beaches. Long period westerly swell will bring an increased risk for sneaker waves and strong rip currents with breaking waves of 14 to 19 feet. Remember: stay off of jetties, piers, rocks, and other waterside infrastructure, remain out of the water, and never turn your back on the ocean! && .MTR WATCHES/WARNINGS/ADVISORIES... CA...Beach Hazards Statement through this evening for CAZ006-505-509- 529-530. Coastal Flood Advisory from 9 AM this morning to 1 PM PST this afternoon for CAZ506. PZ...Small Craft Advisory until 3 PM PST this afternoon for Pigeon Pt to Pt Pinos 0-10 nm-Pt Arena to Pt Reyes 0-10 nm-Pt Pinos to Pt Piedras Blancas 0-10 nm.
