Category 1 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-09-20

Category 1

WHAT
No flooding risk is forecast (Category 1). Relatively modest tidal levels and near-normal pressure are keeping conditions routine.

WHEN
Peak water levels occur mid-afternoon around 3:00 PM, but no issues are expected.

IMPACTS
- No impact anticipated.

REASONING
Tide was the main contributing factor, though it remained moderate. Pressure was slightly above normal and wind offered little onshore influence. Overall, this matches similar conditions on 2026-08-18 (Cat 1).

Day 2: 2026-09-21

Category 1

WHAT
Conditions remain at Category 1 with no indication of flooding. Tides are ordinary, and slightly lower pressure is not enough to raise concerns.

WHEN
Highest tide will occur in mid-afternoon near 3:36 PM, but no flooding is expected.

IMPACTS
- No impact anticipated.

REASONING
Modest tidal height is again the biggest factor, but still well below flood thresholds. Pressure is near normal and wind remains minimal. This closely resembles 2021-08-06 (Cat 1).

Day 3: 2026-09-22

Category 1

WHAT
Still no flooding risk (Category 1). Typical tides and normal conditions continue, with minimal onshore wind.

WHEN
Peak tide will occur late afternoon around 4:06 PM, without any flood threat.

IMPACTS
- No impact anticipated.

REASONING
Moderate tide levels remain the primary driver. Below-normal pressure has a slight influence, but not enough to raise risk. No onshore wind or king tide factors are present. The day’s forecast is similar to 2026-09-06 (Cat 1).
