Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-04

CATEGORY 2

WHAT
Category 2 indicates no flooding risk is expected. The moderate tidal height is the main driver, with a small contribution from slightly below-normal atmospheric pressure but minimal wind influence.

WHEN
The highest water levels will occur around midday near 12:36 PM and again in the late evening near 10:24 PM.

IMPACTS
• No impact anticipated.

REASONING
The tide was the primary factor, with a minor boost from below-normal pressure. Wind and other factors contributed little to overall risk.

Day 2: 2026-09-05

CATEGORY 1

WHAT
Category 1 means no flooding risk. Tidal conditions are relatively modest, and no significant wind or pressure anomalies are present.

WHEN
Peak tides are expected around mid-afternoon near 2:18 PM and late at night near 11:36 PM.

IMPACTS
• No impact anticipated.

REASONING
The tide is the main factor, but it remains well below any concerning levels. Pressure is near normal, and wind effect is negligible. This is similar to the 2022-07-01 Cat 1 event.

Day 3: 2026-09-06

CATEGORY 2

WHAT
Category 2 again signals no risk of flooding. A moderately high tide is driving most of the classification, with negligible onshore wind influence.

WHEN
Elevated water levels will peak in the afternoon, around 3:24 PM.

IMPACTS
• No impact anticipated.

REASONING
Moderate tidal conditions remain the main driver, with only a slight effect from below-normal pressure and minimal wind contribution.
