Category 2 · NO FLOODING EXPECTED
# Flood Watch

**Redondo Beach, WA**

Day 1: 2026-09-03

CATEGORY 2

WHAT
A Category 2 event with no flooding risk expected. Higher-than-average tidal levels are the main driver, with a slight boost from somewhat lower atmospheric pressure.

WHEN
Peak water levels are expected late morning around 10:54 AM and again in the evening near 9:30 PM.

IMPACTS
• No impact anticipated.

REASONING
The tide contributed most to the classification, with a modest effect from slightly below normal pressure. Winds were negligible, and all models agree on Category 2 with no higher tail outcome.


Day 2: 2026-09-04

CATEGORY 2

WHAT
Another Category 2 day with no risk of flooding. Tidal influence is still the biggest contributor, although pressure remains near normal and wind has minimal effect.

WHEN
Look for the highest tides around midday near 12:36 PM and later that night around 10:24 PM.

IMPACTS
• No impact anticipated.

REASONING
The moderate tide level leads the classification, with near-normal pressure and very little wind contribution. The ensemble shows no spread beyond Category 2.


Day 3: 2026-09-05

CATEGORY 1

WHAT
A routine Category 1 day indicating no flooding risk. Moderate tides combined with normal pressure and slightly offshore wind produce minimal concern.

WHEN
Peak levels in mid-afternoon around 2:18 PM and again late at night near 11:36 PM.

IMPACTS
• No impact anticipated.

REASONING
Tides are moderate, with near-normal pressure and a slight offshore wind reducing any onshore push. This is similar to the 2025-09-19 Cat 1 event. All model members agree on Category 1.
