Category 1 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-21

CATEGORY 1

WHAT
A routine day with no flooding risk. The tide will be modest, and pressure is close to normal, keeping overall conditions stable.

WHEN
Peak water levels will occur around 12:54 AM and again near 3:36 PM.

IMPACTS
• No impact anticipated.

REASONING
Tide and slightly below-normal pressure both contributed modestly, but neither is high enough to cause a flood threat. Wind showed virtually no effect. This outlook aligns with past Category 1 days, such as 2026-08-26.

Day 2: 2026-09-22

CATEGORY 1

WHAT
Another routine day with no flooding expected. Tides remain moderate, and pressure is near normal, so conditions are not conducive to flooding.

WHEN
Peak water levels will occur around 2:06 AM and again near 4:06 PM.

IMPACTS
• No impact anticipated.

REASONING
Slight tidal influence combined with minimal onshore wind keeps the risk low. Pressure remains stable, limiting any further rise in water levels. These factors align with other Category 1 analog events, such as 2026-09-06.

Day 3: 2026-09-23

CATEGORY 1

WHAT
No flooding risk is anticipated. Astronomical tide is somewhat elevated, but the pressure is relatively normal, and wind remains light.

WHEN
Peak water levels will occur around 3:00 AM and again near 4:30 PM.

IMPACTS
• No impact anticipated.

REASONING
A moderate high tide is the main factor, but not enough to cause concern. Pressure and wind contribute very little, so water levels are unlikely to reach flood thresholds. Historical days with similar conditions also stayed at Category 1, such as 2025-09-12.
