Flood Watch

Redondo Beach, WA

Day 1: 2026-04-20

CATEGORY 3

WHAT
A moderate high tide, combined with slightly lower pressure than usual, brings the forecast close to flood conditions. While widespread flooding is not expected, be aware of possible minor water overflow along the immediate shoreline.

WHEN
Peak concern around the early morning high tide near 6:36 AM, and again in the evening around 9:06 PM.

IMPACTS
• Minor inundation possible at the immediate shoreline.

REASONING
Higher-than-usual tide levels are the main driver, with a mild boost from below-normal pressure. Wind does not contribute much. This is similar in magnitude to the 2023-12-27 Cat 3 event.

Day 2: 2026-04-21

CATEGORY 2

WHAT
Routine conditions with no significant flooding risk. Tides will still be somewhat elevated, but no flooding impacts are expected.

WHEN
High tides occur in the early morning near 7:24 AM and again in the late evening around 10:12 PM.

IMPACTS
• No impact anticipated.

REASONING
Moderate tide levels and slightly below-normal pressure combine, but not enough to produce a flood threat. Onshore wind influence is minimal. This forecast is slightly lower than the similar 2023-01-06 Cat 3 event, so a Category 2 classification is expected.

Day 3: 2026-04-22

CATEGORY 2

WHAT
Again, no risk of flooding is indicated despite moderate tides. Conditions remain routine along the shoreline.

WHEN
Elevated tides in the morning around 8:18 AM, then late at night near 11:24 PM.

IMPACTS
• No impact anticipated.

REASONING
Moderate tide activity is offset by near-normal pressure and weak onshore wind. Past events with similar tides and slight pressure anomalies were sometimes higher category, but in this forecast, conditions remain at Category 2.

PRECAUTIONARY/PREPAREDNESS ACTIONS...
