Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-10

CATEGORY 2

WHAT A Category 2 forecast indicates routine tidal conditions with no flooding expected. Slightly above-average tide combined with near-normal pressure are driving the classification, while onshore wind remains minimal.

WHEN Peak water levels are expected early in the morning around 4:30 AM and again in the late afternoon near 5:42 PM.

IMPACTS • No impact anticipated.

REASONING Tide height was the main contributor, with a slight boost from below-normal pressure. Wind offered very little influence. One of the closest analog days was 2026-02-01, which was a Category 3 event and thus higher than the current forecast.

Day 2: 2026-09-11

CATEGORY 2

WHAT Once again, conditions remain at Category 2, indicating no flooding risk. Moderate tides and near-normal pressure characterize the day, while onshore winds are fairly low.

WHEN Expect the highest tides around 5:24 AM and another peak near 6:06 PM.

IMPACTS • No impact anticipated.

REASONING Tide is the primary factor, with slightly below normal pressure lending a minor supportive effect. Wind contribution is essentially zero. Among the similar historical days is 2026-02-01 at Category 3, which exceeds this forecast’s Category 2.

Day 3: 2026-09-12

CATEGORY 2

WHAT Category 2 conditions persist, meaning no flood threat. Elevated tides lead the forecast, though pressure is only modestly below normal, and wind remains minimal.

WHEN High tide is expected in the morning near 6:12 AM and in the early evening around 6:36 PM.

IMPACTS • No impact anticipated.

REASONING The tide continues to be the largest driver, with slightly lower pressure a minor factor. Wind contribution is negligible. A close analog date was 2026-01-06, which reached Category 3, higher than this Cat 2 forecast.
