Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-10

CATEGORY 2

WHAT
We remain in Category 2, indicating routine conditions with no flooding risk. Tides are moderately high, and atmospheric pressure is near normal.

WHEN
Peak high tides in the early morning around 4:30 AM and late afternoon near 5:42 PM.

IMPACTS
• No impact anticipated.

REASONING
Tide was the main factor, with slight support from near-normal pressure. Light onshore winds contributed a negligible or slightly negative effect. All forecast models agree on Category 2, so no higher-end scenario is expected.

Day 2: 2026-09-11

CATEGORY 2

WHAT
Continuing at Category 2, conditions remain routine with no flooding risk. Tidal influences are the primary driver, and winds are not significant enough to increase the risk.

WHEN
Peak high tides early in the morning around 5:24 AM and again in the early evening near 6:06 PM.

IMPACTS
• No impact anticipated.

REASONING
A moderately high tide is the biggest factor. Pressure is slightly above low-risk thresholds, and wind has little net effect. One similar past event, on 2026-02-01, reached Category 3, which is higher than today’s classification, but no model scenarios indicate a jump beyond Category 2.

Day 3: 2026-09-12

CATEGORY 2

WHAT
Again at Category 2, no flooding risk is indicated. Elevated tide levels are expected, but the overall impact remains minimal.

WHEN
Peak risk occurs around the early morning high tide near 6:12 AM and late afternoon high tide around 6:36 PM.

IMPACTS
• No impact anticipated.

REASONING
High tide remains the main contributor, with a small boost from below-normal pressure, while wind impact is slightly negative. A similar past date, 2026-01-06, was a Category 3 event, which exceeds today’s classification, but forecast models consistently stay at Category 2.
