Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-23

CATEGORY 1

WHAT
No flooding risk is expected. Tidal levels are moderate and pressure remains near average, keeping the day in a routine state.

WHEN
Peak tidal levels occur in the early morning near 3:00 AM and again in the late afternoon around 4:30 PM.

IMPACTS
• No impact anticipated.

REASONING
The moderate high tide was the main factor, with near-normal pressure and very light onshore wind offering no additional push toward flood conditions. This matches past Cat 1 days such as the 2025-10-03 event.

Day 2: 2026-09-24

CATEGORY 2

WHAT
No flood risk is expected. A slightly higher tide and mildly below-normal pressure do not appear enough to cause any problems, especially with an offshore wind component reducing water buildup.

WHEN
Highest concern would be around the afternoon high tide, near 4:48 PM.

IMPACTS
• No impact anticipated.

REASONING
A modestly elevated tide combined with slightly lower pressure led to a small increase from Category 1, yet the offshore wind reduced onshore surge. Ensemble models all concur on Category 2, with no higher tail risk.

Day 3: 2026-09-25

CATEGORY 2

WHAT
No flooding risk is expected again. Slightly greater tide levels plus somewhat lower pressure still remain well short of flood thresholds, and onshore wind is not strong enough to push conditions higher.

WHEN
Peak tides will occur around 5:06 AM and in the late afternoon near 5:06 PM.

IMPACTS
• No impact anticipated.

REASONING
Moderate tides and mildly below-normal pressure are the main drivers here. Although there is a moderate onshore breeze, it does not significantly boost water levels. The ensemble agrees on Category 2 with no higher tail scenario.
