Flood Watch

Redondo Beach, WA

Day 1: 2025-11-11

CATEGORY 2

WHAT
No significant coastal flooding is expected. Highest tide is forecast around 19.8 ft, but barometric pressure remains relatively high near 1018 hPa, and NOAA’s daily flood likelihood is extremely low (about 0.1%).

WHEN
Highest tide and very minimal flood concern around mid-morning (approximately 10:30 AM PST).

IMPACTS
No flooding impacts are anticipated. Low-lying areas may observe minor ponding, but conditions are not expected to rise to a flood event.

ADDITIONAL DETAILS...

Compared to historical Category 3 events—when tides exceeded 20 ft and NOAA’s likelihood was notably higher—today’s data do not indicate similarly stressful conditions. The barometric pressure is significantly above the 992.8 hPa threshold typically associated with more severe storm-driven flooding.


Day 2: 2025-11-12

CATEGORY 2

WHAT
No significant flooding is expected. The peak tide is around 19.6 ft with barometric pressure remaining above 1015 hPa, and NOAA reports a 0.0% flood likelihood.

WHEN
Highest tide near late morning (approximately 11:30 AM PST).

IMPACTS
No inundation along the shoreline or nearby areas is anticipated. Minor water accumulation may occur in extremely low-lying spots, but no impactful flooding is forecast.

ADDITIONAL DETAILS...

Historical moderate- or high-risk flood events have involved significantly low barometric pressure (below ~1000 hPa). In this case, the barometric pressure is comfortably higher, and NOAA’s data underscore minimal flood risk.


Day 3: 2025-11-13

CATEGORY 2

WHAT
No notable coastal flooding is anticipated despite relatively high tides (near 19.6 ft again). Barometric pressure around 1019 hPa and NOAA’s flood likelihood of 0.0% suggest low flood potential.

WHEN
Highest tide around midday (approximately 12:30 PM PST).

IMPACTS
Little to no flooding impact. Minor water pooling may be observed along very low-lying shorelines, but conditions are not close to a typical flood scenario.

ADDITIONAL DETAILS...

Historically, Category 3 or above required a combination of higher tides (exceeding ~20 ft) and a significantly lower barometric pressure. This forecast remains well above pressure thresholds known to exacerbate tidal flooding, and wind direction is not from the more concerning W/NW sector at high speeds.


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
