Flood Watch

Redondo Beach, WA

Day 1: 2026-09-02

CATEGORY 3

WHAT Category 3 conditions are expected, close to flood thresholds. Elevated tidal levels are the main driver, with somewhat lower pressure providing additional support.

WHEN Peak risk is around the morning high tide near 9:36 AM and again in the evening near 8:48 PM.

IMPACTS • Minor inundation possible at the immediate shoreline.

REASONING The relatively high astronomical tide was the primary reason for the Category 3 rating, with modest influence from slightly below-normal pressure. Onshore wind contributed little. This is similar to the 2026-01-07 Cat 3 event.

Day 2: 2026-09-03

CATEGORY 2

WHAT No flooding risk expected. Routine tides and normal pressure keep conditions stable.

WHEN Highest water levels around 10:54 AM and 9:30 PM.

IMPACTS • No impact anticipated.

REASONING Tide and modestly below-normal pressure contributed, but minimal onshore wind leaves the day in a routine Category 2 range. Models show consistent agreement at this category.

CATEGORY 1

WHAT No flooding risk expected. Tidal levels and pressure remain near typical values.

WHEN High tides around 12:36 PM and again near 10:24 PM.

IMPACTS • No impact anticipated.

REASONING Moderate tide and average pressure keep the day at Category 1. Wind factor is negligible. This is similar to the 2025-09-05 Cat 1 event.
