Flood Watch

Redondo Beach, WA

Day 1: 2024-11-12

CATEGORY 3

WHAT Minor coastal flooding possible. High tides may cause water levels to rise near shorelines and low-lying areas.

WHEN From 12:00 PM to 2:00 PM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures are unlikely but possible.

ADDITIONAL DETAILS...

• Barometric Pressure: The mean barometric pressure during the high tide at 1:36 PM is 1022.56 hPa, which is significantly higher than in historical severe flood events. This suggests stable weather conditions with a lower likelihood of significant flooding.
• Tide Height: The tide is projected to reach approximately 19.991 ft at its peak, which is lower than the 21 ft threshold associated with higher flood risks. This height is similar to the Category 3 historical event on 12/27/2023.
• Wind Direction and Speed: Winds are expected to be from the SSW at around 10-13 mph. This moderate wind speed and direction are not expected to significantly impact flooding potential.
• NOAA Flood Likelihood: NOAA indicates a low flood likelihood of 0.2% for this date, with a distance to the flooding threshold of -1.27 m, suggesting minimal risk.

Day 2: 2024-11-13

CATEGORY 3

WHAT Minor coastal flooding possible. Elevated tides may affect shorelines and low-lying areas.

WHEN From 12:30 PM to 2:30 PM PST.

IMPACTS Minor flooding of low-lying areas. Property damage is not expected, but caution is advised for those in vulnerable locations.

ADDITIONAL DETAILS...

• Barometric Pressure: The mean barometric pressure during the high tide at 2:06 PM is 1016.45 hPa. While lower than Day 1, it remains above the critical low-pressure threshold observed in severe historical events.
• Tide Height: The tide is expected to peak at approximately 20.217 ft, which is below the 21 ft level associated with higher flood risks but slightly higher than Day 1's peak.
• Wind Direction and Speed: Winds are forecasted from the SSE at 8-13 mph. This wind pattern does not significantly contribute to increased flood risk.
• NOAA Flood Likelihood: NOAA reports a low flood likelihood of 1.4% for this date, with a distance to the flooding threshold of -0.95 m, indicating a low risk of flooding.

Day 3: 2024-11-14

CATEGORY 3

WHAT Minor coastal flooding possible due to elevated high tides impacting shorelines and low-lying regions.

WHEN From 1:00 PM to 3:00 PM PST.

IMPACTS Minor flooding concerns for low-lying areas. No significant property damage is anticipated.

ADDITIONAL DETAILS...

• Barometric Pressure: The mean barometric pressure during the high tide at 2:42 PM is 1019.21 hPa, indicating stable atmospheric conditions not conducive to severe flooding.
• Tide Height: The tide is projected to reach approximately 20.324 ft at its highest, still below the critical 21 ft threshold for major flooding concerns.
• Wind Direction and Speed: Anticipated winds from the S at 9-14 mph are moderate and unlikely to exacerbate flooding risk significantly.
• NOAA Flood Likelihood: NOAA's flood likelihood is low at 1.7%, with a distance to the flooding threshold of -0.91 m, suggesting minimal flooding potential.

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.
