Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-14

CATEGORY 2

WHAT
A routine day (Category 2), with no flooding risk expected. Moderate tide is the primary driver, and pressure is near normal.

WHEN
Main high tides occur around 8:00 AM and again near 7:30 PM.

IMPACTS
• No impact anticipated.

REASONING
The moderate astronomical tide contributed most to today’s classification, with only a small boost from pressure. Onshore wind played a minimal role. Ensemble forecasts agree on Category 2, so no higher-end outcome is expected.

Day 2: 2026-09-15

CATEGORY 2

WHAT
Another routine day (Category 2), with no flooding risk. Tides remain somewhat elevated, while pressure is slightly below normal. Wind has little effect overall.

WHEN
High tides peak mid-morning around 8:54 AM and again in the evening near 8:00 PM.

IMPACTS
• No impact anticipated.

REASONING
Tide and slightly lower pressure raise water levels modestly, but wind actually subtracts a small amount from the total. Although the ensemble’s central estimate was Category 1, nearly half of the models support Category 2, which is reflected in the official classification.

Day 3: 2026-09-16

CATEGORY 1

WHAT
Category 1 indicates no flooding risk, with somewhat lower tides and near-normal pressure.

WHEN
High tide mid-morning around 9:54 AM and again in the evening near 8:30 PM.

IMPACTS
• No impact anticipated.

REASONING
Both tide and pressure factors are mild, and wind is minimal. Conditions closely resemble the 2021-07-09 Category 1 event.
