The tropical Pacific Ocean is warmer right now than it has ever been recorded for this date, and it's still strengthening. Climate scientists expect it to peak as a "very strong" or possibly the strongest El Niño on record — stronger than the famous 1982-83 and 1997-98 events. The term "super El Niño" refers specifically to that ocean warmth, not to a guaranteed outcome on land: El Niño doesn't cause storms directly, but it shifts the odds toward a wetter, stormier winter for California and toward significantly elevated coastal flood risk.

Importantly, none of the panelists offered guarantees. The strong 2015-16 El Niño, for comparison, was real and powerful in the ocean but didn't produce an especially wet winter in California. The panel's consistent message: this year raises the odds of serious impacts, and the responsible move is to prepare now, not to panic.

The panel's highest-confidence prediction, repeated by multiple speakers, is coastal flooding — driven by the combination of El Niño-elevated sea levels, decades of background sea-level rise, bigger winter waves, and King tides all stacking on top of each other around the same time.

• Coastal erosion and flooding along the outer coast. Panelists described beaches statewide retreating roughly 30 meters landward during past El Niño events, with more wave energy reaching the shoreline and undercutting bluffs. That's directly relevant to Point Reyes, Bolinas, Stinson Beach, and Dillon Beach.
• Elevated sea levels, including inside San Francisco Bay. Scripps oceanographer Dr. Mark Merrifield said Bay water levels rise in tandem with the open coast — historically by half a foot to a foot during big El Niño events — peaking around November through winter. That affects Marin's bayside communities as much as the outer coast.
• King tides around Christmas. The tidal cycle happens to peak at the same time as El Niño this year, which panelists called an "unlucky coincidence" that will compound high-water events.
• Algal blooms and domoic acid. A viewer from Stinson Beach asked about sea lions affected by algal blooms in recent weeks. The state, working with California's crab fleet, will begin domoic acid testing in about 60 days ahead of Dungeness crab season, and officials are anticipating higher-than-average domoic acid levels because of the warmer water.
• Cell and landline coverage in rural West Marin. A viewer from Point Reyes Station raised the lack of cell coverage across much of West Marin and the North Coast, and asked whether copper landlines — often the only working lifeline in these areas — would be protected. Sen. McGuire said he has killed AT&T-backed legislation to eliminate copper landlines twice as Senate President Pro Tem, and that AT&T is now petitioning the Trump administration to end landline service obligations in California; he committed to continuing to fight it.
• Creeks draining to the Bay (relevant to Marin's watersheds). Asked about local creeks that drain into the Bay, KTVU meteorologist Mark Tamayo said the real risk isn't one storm — it's storms landing back-to-back without a break in between, which can "supercharge" creeks quickly. A single strong storm followed by a lull is manageable; a tight sequence of storms is the scenario to watch for.
• Fall fire/lightning risk before the rains arrive. A Sausalito viewer asked whether this El Niño could affect fire, wind, or fall lightning risk. Tamayo said increased tropical moisture and atmospheric instability moving up the coast this fall could raise the chance of thunderstorms and dry-lightning-sparked fires, on top of already hot, dry conditions — a concern that exists independent of, and ahead of, any winter rain.
• Wind storms. Increased odds of winter wind events statewide, though panelists said there isn't much formal research tying specific wind patterns to El Niño, and it's not possible to say which stretch of coast will be hit hardest.
• Timing. The consistent message: this is a "back-weighted" event. Expect the most significant impacts from late December into January, February, and March rather than an early start to the rainy season. Warmer, more humid coastal air and less coastal fog are already showing up now, ahead of the bigger winter impacts.
• Historical rainfall comparison for the North Coast: 161% of average rainfall in 1982-83, and 116% of average in 2015-16. Given this year's record ocean warmth, Tamayo said those numbers could be exceeded, though he cautioned that Southern California currently has better odds in the official outlook than Northern California.

Recommendations came mainly from Cal OES's Nate Ortiz, echoed by the other panelists:

• Sign up for local emergency alerts now, through your county (search "Ready California" or visit ListosCalifornia.org and enter your county).
• Because cell coverage is unreliable across much of West Marin, don't rely on phone alerts alone — make sure you know your county's other alert channels, and keep a landline connection if you have one.
• Build a grab-and-go bag: passports, Social Security cards, birth certificates, insurance cards, prescription lists, and some cash (point-of-sale and ATM systems fail when the power goes out).
• Build an emergency supply kit incrementally — it doesn't have to happen all at once. Aim for the ability to be self-sufficient for 72 hours; a rough guide is one gallon of water per person per day.
• Make a plan for pets: carriers/kennels, food, leashes, medications.
• Talk with your family now about what to do if you're not together when an emergency hits — where to meet, how to communicate.
• Keep vehicles fueled or charged and mobile devices charged.
• Check your flood insurance now if you're in a flood zone. Many Californians in high-flood-risk areas don't carry it. This isn't a prediction that you'll flood this year — it's a reminder that the odds are higher, and insurance takes time to kick in.
• Know your neighbors — especially anyone with mobility or access needs who may need extra time to evacuate. Cal OES's Ortiz noted that for people with longer evacuation timelines, the trigger to leave should come earlier, not at the last minute.
• Watch for Public Safety Power Shutoff (PSPS) events. Cal OES is coordinating with utilities, including PG&E, on grid hardening and faster restoration, though panelists acknowledged utilities still have work to do here.

• Opened and closed the town hall, framing it as an effort to separate "hype from reality."
• Highlighted the $10 billion climate resilience bond California voters approved in 2024 — the largest state climate investment in U.S. history — funding flood infrastructure, watershed restoration, and coastal/wildfire preparedness.
• Noted Cal OES staffing and Cal Fire firefighter numbers have roughly doubled over the past decade (Cal Fire from 6,700 to more than 14,000 firefighters).
• Fielded the West Marin landline/cell coverage question directly: said he has killed AT&T-backed legislation to eliminate copper landlines twice as Senate President Pro Tem, and pledged to keep fighting AT&T's current push to end landline obligations in rural California.

• Explained El Niño as a temporary warming of the tropical eastern Pacific Ocean that shifts the Pacific storm track rather than causing storms directly.
• Said this event is already strong and forecast to strengthen into a "very strong" or "super" El Niño — potentially the strongest on record, with ocean temperatures in the key monitoring region warmer than any previously recorded for this date.
• Stressed that El Niño never guarantees a specific outcome — the very strong 2015-16 event did not produce an especially wet California winter — but an event this strong meaningfully shifts the odds toward a wetter winter, especially in Southern California but likely Northern California too.
• Said impacts will likely be "back-weighted," peaking from late December through March, driven by an increased likelihood of clustered, back-to-back storm sequences ("atmospheric river families") rather than any single mechanism.
• Called coastal flooding the highest-confidence risk of the winter.
• Recommended people consider flood insurance now, and said he's personally kept his January–March calendar open in case of major events.

• Grew up in Marin County and shared that he was evacuated from his childhood home during a storm the year before the 1982-83 El Niño — a reminder that damaging storms can happen in any year, El Niño or not.
• Cautioned against media hype, noting the official seasonal outlook is currently fairly modest ("equal chances" for the North Coast/Bay Area) even though that could shift with updates later this year.
• Cited historical North Coast rainfall during past strong El Niños — 161% of average in 1982-83, 116% of average in 2015-16 — and said this year could exceed those totals given record ocean warmth, while cautioning that Southern California currently has better odds in the official outlook.
• Said his biggest concern is storm sequencing: back-to-back storms without recovery time in between are what "supercharge" rivers (like the Russian River) and local creeks, more so than any single storm.
• Flagged increased tropical moisture and atmospheric instability this fall as a dry-lightning and fire concern, on top of already hot, dry conditions — independent of and ahead of any winter rain.
• Said increased tropical-storm activity in the Pacific is likely this fall, with some chance of a system approaching California.

• Said sea levels are already elevated and likely headed toward the highest ever recorded on the California coast this winter, compounded by King tides peaking around Christmas.
• Explained that San Francisco Bay and harbor water levels rise in tandem with the open coast, so Bay communities should expect similar increases — historically half a foot to a foot during major El Niño events.
• Described high waves and beach/cliff erosion as a near-certain outcome, with beaches retreating roughly 30 meters landward in past strong El Niño events.
• Outlined marine ecosystem impacts: a marine heat wave already underway that El Niño will deepen, suppressed upwelling that will stress the food web, particular stress on immobile species like kelp (already hard-hit off Sonoma, Mendocino, and Humboldt), and northward range shifts for mobile species like tuna and squid.
• Distinguished El Niño (a natural, recovering cycle) from climate change (a non-cyclical, compounding trend), describing this El Niño as a "stress test" for conditions climate change will eventually make the norm.

• Described Cal OES's role coordinating state, local, tribal, and federal resources during disasters, and its shift toward proactively pre-positioning equipment and personnel ahead of anticipated events, as it already does for wildfire season.
• Gave the bulk of the practical household-preparedness advice: build a grab-and-go bag, aim for 72-hour self-sufficiency (roughly one gallon of water per person per day), sign up for local emergency alerts, make a family communication plan, consider flood insurance, and keep vehicles fueled/charged.
• Encouraged residents to plan for pets and to check in on neighbors with mobility or access needs, who may need more lead time to evacuate.
• Noted Cal OES is coordinating with utilities, including PG&E, on Public Safety Power Shutoff (PSPS) events and grid hardening, while acknowledging utilities still have work to do.
• Pointed residents to ListosCalifornia.org (or "Ready California") to find county-specific alerts and resources.

Nothing is guaranteed, but this is shaping up to be a genuinely unusual event — potentially the strongest El Niño on record — and the panel's consistent advice was to treat August as prep time rather than wait for the first storm. For West Marin, the top watch-items are coastal erosion and flooding along the outer coast, elevated Bay water levels, back-to-back storm sequences that could overwhelm local creeks, patchy cell/landline coverage complicating alerts, and a possible fall window of dry-lightning fire risk before the rainy season fully arrives.
