Flood Watch

Redondo Beach, WA

Day 1: 2025-09-24

CATEGORY 2

WHAT
No risk of flooding is currently expected. While tide levels will be relatively high (peaking around 18.5 ft), the barometric pressure is well above the historically low thresholds (near 992.8 hPa). NOAA indicates a 0% flood likelihood, suggesting conditions remain below flood-triggering thresholds.

WHEN
Highest tide near 17:48 (5:48 PM), with barometric pressure around 1006.45 hPa.

IMPACTS
No significant impacts anticipated. Low-lying areas are unlikely to see any inundation based on the available data.

ADDITIONAL DETAILS...

Barometric pressure, though somewhat moderate in the early morning (around 1001.71 hPa), is still not low enough to elevate flood concerns. Historically, significantly lower pressures and higher tides (>20 ft) were present during Category 3+ events. In contrast, NOAA’s 0% flood likelihood further confirms minimal risk for this date.


Day 2: 2025-09-25

CATEGORY 2

WHAT
No risk of flooding is forecast. Tidal heights will again approach 18 ft, but barometric pressure will be higher (around 1020.32 hPa at the evening high tide).

WHEN
Highest tides around 07:12 AM (with 1012.55 hPa) and 06:00–06:36 PM window (barometric pressure ~1020.32 hPa).

IMPACTS
No notable impacts are expected as neither tide heights nor barometric conditions indicate a close-to-flood event.

ADDITIONAL DETAILS...

Comparison to historical Category 3 or 4 events (which featured tides often above 20 ft and much lower pressures) confirms minimal flood likelihood. NOAA’s official forecast reports a 0% flood likelihood for 09/25, reinforcing a lack of coastal flood concerns.


Day 3: 2025-09-26

CATEGORY 2

WHAT
No risk of flooding is anticipated. While tides may again approach 18 ft, barometric pressure remains relatively high (around 1017 hPa at the key high tides).

WHEN
Highest tide around 08:00 AM and again in the early evening (around 06:42 PM), both with barometric readings near 1017 hPa.

IMPACTS
No flooding issues expected. Low-lying roadways and shoreline structures are not projected to experience inundation.

ADDITIONAL DETAILS...

All major flood indicators—particularly barometric pressure and tide levels—remain below historical flood-event thresholds. NOAA’s 0% likelihood for 09/26 substantiates that conditions will not favor coastal flooding.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

CATEGORY KEY
