Flood Watch

Redondo Beach, WA

Day 1: 2025-10-15

CATEGORY 2

WHAT
No flooding is expected. Tides may reach around 19.2 feet, but the barometric pressure is notably high, and NOAA’s flood likelihood is 0%. Conditions do not suggest coastal flooding.

WHEN
Peak tides expected late morning to early afternoon.

IMPACTS
No flooding impacts anticipated. Normal beach and shoreline conditions expected.

ADDITIONAL DETAILS...

Comparing Day 1’s maximum tide (~19.2 ft) and high barometric pressure (~1028 hPa) with historical coastal flooding events shows that the pressure is much higher than in previous flood scenarios. NOAA has indicated a low flood likelihood (0%), reinforcing the conclusion that Day 1 poses no significant flood risk.


Day 2: 2025-10-16

CATEGORY 2

WHAT
No flooding is expected. Although tide levels may again approach ~19.3 feet, barometric pressure remains very high (~1031.8 hPa), sharply reducing flood potential.

WHEN
Highest tide expected around midday to early afternoon.

IMPACTS
No coastal flooding impacts anticipated. Normal activities along shorelines can proceed without concern.

ADDITIONAL DETAILS...

Historically, flood events at or above Category 3 often involved significantly lower barometric pressures (below ~1005 hPa), sometimes around or below 992 hPa. In contrast, the very high pressures and NOAA’s 0% flood likelihood suggest no concerns for flooding on Day 2.


Day 3: 2025-10-17

CATEGORY 2

WHAT
No flooding is expected despite tides once more nearing 19.3 feet. Mean sea level pressure remains high (~1028 hPa), and NOAA continues to forecast a 0% likelihood of flooding.

WHEN
Peak tidal heights during midday and early afternoon hours.

IMPACTS
No beach or coastal roadway impacts anticipated. Conditions are expected to remain normal with no risk of inundation.

ADDITIONAL DETAILS...

Day 3’s conditions align with the pattern of high atmospheric pressure and tide levels below the historical threshold (generally above 20 feet) for significant flooding. These factors, combined with NOAA’s assessment, place Day 3 at a no-risk category.

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
