Flood Watch

Redondo Beach, WA

Day 1: 2025-08-12

CATEGORY 3

WHAT
Close to a flood event and worth monitoring, but unlikely to cause any flood damage. Although the afternoon and evening high tide will approach 20 ft, overall barometric pressure is not low enough to significantly increase flood risk.

WHEN
From approximately 6:00 PM to 9:00 PM PST (highest tide forecast around 7:12 PM).

IMPACTS
Minor ponding of water possible in very low-lying areas. No major roadway closures or property damage expected based on current data and NOAA’s 0% flood likelihood.

ADDITIONAL DETAILS...

Barometric pressure near 1007 hPa is well above the critical low-pressure benchmark (around 992.8 hPa). While the tide levels (near 19.95 ft) are higher than some past Category 3 events, NOAA’s forecast of 0.0% flood likelihood strongly suggests no significant flooding. This is similar to historical Category 3 conditions (e.g., 12/27/2023) when barometric pressure was also above 1000 hPa and tide heights were substantial but did not result in major flooding.


Day 2: 2025-08-13

CATEGORY 3

WHAT
Close to a flood event and worth monitoring. Tide heights again approach 20 ft, but barometric pressure and NOAA’s data do not indicate an elevated flood threat.

WHEN
Highest tide expected around 7:42 PM through 8:00 PM.

IMPACTS
Potential for very minor inundation along shoreline edges, but widespread flooding or property damage remains unlikely. No significant road closures anticipated.

ADDITIONAL DETAILS...

Barometric pressure remains moderately low (around 1007 hPa) but not near the critical threshold for severe coastal flooding. NOAA’s official estimate remains 0.0% flood likelihood with more than a meter to spare below the flood threshold. Historically, Category 3 events in this barometric pressure range have not caused substantial flooding unless tides were above 20.5 ft and accompanied by wind currents forcing additional water onshore.


Day 3: 2025-08-14

CATEGORY 3

WHAT
Tide levels will remain high, just under 20 ft, keeping conditions near a flood event threshold. However, pressure around 1004–1005 hPa is still significantly above the severe low-pressure mark, limiting overall flood potential.

WHEN
Strongest tidal influence forecast near 8:18 PM.

IMPACTS
Low-lying areas along the immediate waterfront could experience minor water encroachment. Widespread impacts and property damage are not expected.

ADDITIONAL DETAILS...

Though the barometric pressure is a bit lower than on previous days (around 1004–1005 hPa), it stays well above historical low-pressure events that have coincided with destructive flooding. NOAA’s flood likelihood remains at 0.0%. Compared with known Category 4 or 5 historical events, both the tide height and barometric pressure for this day are insufficient to elevate concerns beyond Category 3 levels.


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

Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
