Flood Watch

Redondo Beach, WA

Day 1: 2026-04-21

CATEGORY 3

WHAT
A Category 3 event indicates that conditions are close to flood potential. Higher-than-normal tide is the primary driver, with a slight additional effect from below-normal pressure. Winds are minimal and do not significantly exacerbate the situation.

WHEN
Peak risk is around the morning high tide at 7:24 AM and again in the late evening around 10:12 PM.

IMPACTS
• Minor inundation possible at the immediate shoreline.

REASONING
The higher astronomical tide was the main contributor, with modest support from slightly lower-than-usual pressure. Onshore wind made little difference. This day is somewhat similar to the 2023-01-06 Cat 3 event based on tidal and pressure conditions.

Day 2: 2026-04-22

CATEGORY 2

WHAT
A Category 2 classification means no flood risk is expected. Tides are moderately elevated, but pressure is near normal, and winds remain minimal.

WHEN
Highest tides occur around 8:18 AM and again late at night at 11:24 PM.

IMPACTS
• No impact anticipated.

REASONING
The tide is moderately high, with near-normal pressure and negligible wind influence. The ensemble models fully agree on Category 2. One of the closest analogs was the 2023-01-06 Cat 3 event, which exceeds today’s category.

Day 3: 2026-04-23

CATEGORY 1

WHAT
A Category 1 event indicates no risk of flooding. Tides are lower, and the pressure is somewhat above normal.

WHEN
Peak high tide is in the morning around 9:24 AM.

IMPACTS
• No impact anticipated.

REASONING
The relatively modest tide and calm weather factors maintain a low classification. Pressure is near or above normal, and wind contribution is minimal. This is similar to the 2024-03-02 Cat 1 event.
