Maya: Good morning, Mahrin County. It's Tuesday, October sixth, twenty twenty-six, and this is your Mahrin Morning Briefing.

Devon: Maya, we're starting the day with two weather alerts on the board, so let's not waste any time. It's a hot one again, and the bay shoreline has its own warning.
Maya: First, the weather week ahead. Today is sunny with a high near eighty-eight degrees and a low tonight around fifty-two. And heads up if you're on the coast early: the National Weather Service has a Dense Fog Advisory for the North Bay coast, including Point Reyes, until nine A M. Visibility could drop to a quarter mile, so slow down and give yourself extra drive time.
Devon: And the heat is sticking around. A Heat Advisory stays in effect until ten P M Thursday, covering the North Bay interior valleys and the Bay shoreline. Inland spots could push into the mid-nineties, and with weak onshore flow there won't be much overnight relief. Drink water, check on vulnerable neighbors, and if you can, keep strenuous stuff to the morning or evening.
Maya: Then the cooldown finally arrives. Wednesday tops out at eighty-five, Thursday at eighty-one, and Friday drops sharply to sixty-eight. The weekend looks lovely: Saturday partly cloudy and sixty-five, Sunday mostly sunny and sixty-eight, and Monday back to seventy-one. There's a slight chance of rain, around ten to twenty percent, on most days. Lows stay in the low fifties, so mornings will feel crisp.
Devon: Now the tides. Over the next seven days, the astronomical tides look normal. On the bay side, today's highest tide reaches five point six feet just before nine P M, and on the ocean side it's five point six feet around eight fifteen this evening. The week's biggest tides arrive Sunday, near six point one feet on both sides, and the morning lows will dip a little below zero midweek. Nothing is flagged above normal, so by the calendar alone, tides are within the normal range.
Maya: But the real world is adding a surcharge. The Weather Service has a Coastal Flood Advisory in effect for bayshore locations along San Pablo Bay until one P M Thursday. A storm-driven surge is pushing high tides up to zero point eight feet above normal — tonight's high tide is expected to run about six and a half feet at the San Francisco gauge, and Thursday's could reach nearly six point seven feet. That means water pushing farther up beaches than usual, flooded low-lying parking near the shore, and possible isolated road closures around high tide.
Devon: And here's the bigger picture: Noah, the Climate Prediction Center, says El Nino is strengthening, with a greater than ninety percent chance of a very strong event through the fall and winter, and a seventy-five percent chance it becomes historic, stronger than any since nineteen fifty. A strong El Nino elevates sea levels off our coast, which is exactly the kind of setup that turns ordinary high tides into flood advisories. The next Noah update is due this week, and we'll keep watching it.
Maya: In local news, if you see smoke over the mountain today, don't panic. Firefighters are conducting prescribed burns in the Mount Tamalpais watershed, up to one hundred twenty-three acres near the Sky Oaks Ranger Station and the Bon Tempe Reservoir. It's a planned operation with Mahrin County Fire and Mahrin Water to clear excess vegetation before wildfire season's next act. Expect smoke in parts of the county, and please don't call nine one one just to report it. The Bon Tempe parking lot and nearby roads will be closed during the burns.
Devon: In San Anselmo, police have opened a hate crime investigation after antisemitic graffiti was found at Brookside Elementary School over the weekend. Officers were called Saturday evening and documented the vandalism near the school's multi-purpose room; school staff removed it that same night. As of Sunday, no suspects have been identified, and police believe it happened sometime between Friday's dismissal and Saturday night. The Central Marin Police Authority says there's no place for hatred or intimidation in this community, and they're asking anyone with information to come forward.
Maya: And one for your civic calendar: early voting is underway for the November third election. The county announced that official ballot boxes and vote centers are now open across Mahrin County, so you can vote early or drop off your ballot whenever it's convenient. A reminder that your voice counts before election day, not just on it.
Devon: That's your Mahrin Morning Briefing for Tuesday, October sixth. Stay hydrated through the last of the heat, steer clear of low-lying shore parking around tonight's high tide, and don't be spooked by the smoke over Tam.
Maya: We'll be back tomorrow morning with your update. Have a safe Tuesday, Mahrin.
