Flood Watch

Redondo Beach, WA

Day 1: 2026-09-09

CATEGORY 2

WHAT A routine tide pattern with minimal meteorological influence is forecast. The computed category indicates no flooding risk under current conditions.

WHEN Higher sea levels expected around early morning (near 3:30 AM) and late afternoon (around 5:00–6:00 PM), but no flooding concerns are anticipated.

IMPACTS • No impact anticipated.

REASONING Tide is contributing slightly more than normal but remains well below any flood thresholds. Pressure is near average, and winds are too light to add any notable effect.

Day 2: 2026-09-10

CATEGORY 2

WHAT Another day of routine tides with little meteorological support for flooding. Observed conditions remain safe with no indication of inundation.

WHEN Elevated tide occurs in the pre-dawn hours (around 4:30 AM) and again late afternoon into early evening (around 5:00–6:00 PM).

IMPACTS • No impact anticipated.

REASONING Slightly higher tides dominate the forecast, but pressure is modestly below average and wind is light. Collectively, these factors do not meet flood conditions.

Day 3: 2026-09-11

CATEGORY 2

WHAT Continued routine tidal conditions with negligible wind influence mean no flood risk. The forecast remains calm relative to flood thresholds.

WHEN Peak tide windows fall in the early morning (around 5:00–6:00 AM) and late afternoon to evening (near 6:00 PM).

IMPACTS • No impact anticipated.

REASONING Moderate tides are the main driver, with slightly below-normal pressure and a minimal onshore breeze. Flooding is unlikely as overall factors stay low.
