Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-04

Category 2

WHAT A routine day overall, with a moderate tidal influence as the main driver for a Category 2 classification. Slightly below normal pressure provides a minor contribution, and onshore wind is minimal.

WHEN Highest water levels are expected around midday near 12:36 PM, with a secondary evening peak close to 10:24 PM.

IMPACTS - No impact anticipated.

REASONING Tide is the primary factor responsible for the Category 2 level, with near-normal wind contributing virtually nothing. Pressure is only slightly below average, so it does not significantly increase flood risk. All ensemble members agree on Category 2, indicating a stable forecast.


Day 2: 2026-09-05

Category 1

WHAT A low-key tidal day, leading to a Category 1 classification. Normal-to-high pressure and minimal wind keep flood potential at bay.

WHEN Peak tides occur in the afternoon near 2:18 PM and later at night around 11:36 PM.

IMPACTS - No impact anticipated.

REASONING The moderate tide and above-normal pressure combine for a routine scenario. This is similar to the 2024-08-02 Cat 1 event, underscoring the minimal risk.


Day 3: 2026-09-06

Category 2

WHAT Another day dominated by a moderate high tide, resulting in Category 2 conditions. Wind remains light, and pressure is near normal, so these do not significantly affect flood potential.

WHEN Highest tide is expected in the mid-afternoon near 3:24 PM.

IMPACTS - No impact anticipated.

REASONING Elevated tide levels are the main contributor to reaching Category 2. Both pressure and wind show only small effects, and ensemble forecasts unanimously point to a stable Category 2 outlook.
