Category 1 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-10-17

CATEGORY 1

WHAT Category 1 (no flood risk), driven primarily by a moderate high tide and near-normal atmospheric pressure. Winds are onshore but remain modest and do not pose a flooding threat.

WHEN Peak water levels are expected around late morning near 11:36 AM and again in the evening near 9:24 PM.

IMPACTS • No impact anticipated.

REASONING The moderate tide was the main contributor; pressure remained near normal, and onshore wind was not strong enough to raise concerns. This is similar to the 2026-03-14 Cat 1 event.

Day 2: 2026-10-18

CATEGORY 1

WHAT Another Category 1 day, indicating no flood risk. The tide is somewhat elevated, but high pressure and minimal wind effect keep overall risk low.

WHEN Peak conditions occur around midday at 12:42 PM and late evening near 10:48 PM.

IMPACTS • No impact anticipated.

REASONING A moderate tide plus slightly above-normal pressure lead to a low overall risk. Wind is light and does not contribute to flooding. This is similar to the 2022-09-30 Cat 1 event.

Day 3: 2026-10-19

CATEGORY 1

WHAT Yet another Category 1 day, signifying no flooding concerns. The tide is moderate, and although pressure is a bit lower, it remains well above critical thresholds.

WHEN Highest water still appears around early afternoon near 1:42 PM.

IMPACTS • No impact anticipated.

REASONING The moderate tide is balanced by only slightly below-normal pressure; wind influence is negligible. This is similar to the 2026-07-21 Cat 1 event.
