Category 3 · ELEVATED FLOOD RISK

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-01

CATEGORY 3

WHAT Category 3 conditions are expected, mainly driven by moderately high tidal levels and slightly below-normal pressure. Onshore wind is minimal but still worth some attention as these combined factors bring conditions close to flood thresholds.

WHEN Peak risk around high tide times: morning near 8:30 AM and evening near 8:12 PM.

IMPACTS • Minor inundation possible at immediate shoreline.

REASONING Higher-than-normal tides were the primary contributor, with modest support from below-normal pressure. Onshore wind did not add much. This is similar to the 2026-01-07 Cat 3 event.

Day 2: 2026-09-02

CATEGORY 3

WHAT Category 3 conditions remain in place, again driven mostly by the tide and modestly lower-than-average pressure. Onshore wind remains relatively light.

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

IMPACTS • Minor inundation possible at immediate shoreline.

REASONING The main factor is the moderately high tide, supplemented by pressure that is below normal. Wind did not significantly change conditions. This is similar to the 2026-01-07 Cat 3 event.

Day 3: 2026-09-03

CATEGORY 2

WHAT Conditions downgrade to Category 2, indicating no elevated flood risk. Normal tidal levels and modestly below-average pressure will not pose a concern.

WHEN Peak tides around 10:54 AM and 9:30 PM.

IMPACTS • No impact anticipated.

REASONING Moderate tides and slightly unfavorable pressure were factors but did not elevate the risk enough for flooding. Onshore wind was minimal. Ensemble data does not suggest a worse scenario.
