Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 5:30 AM to 7:30 AM PST and from 5:00 PM to 7:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure during the high tides is significantly higher than the threshold that has historically led to severe flooding events. However, the NOAA Flood Likelihood Analysis indicates a high likelihood of flooding at 6.6%, which, combined with the high tide levels, suggests a potential for minor coastal flooding. The wind direction is not provided, but given the historical data, winds from the W/NW could exacerbate the flood risk.
CATEGORY 2
WHAT Low risk of coastal flooding. No significant inundation expected.
WHEN Highest risk near the time of high tide at approximately 6:30 AM and 7:36 PM PST.
IMPACTS Minimal impacts anticipated. Some water accumulation possible in very low-lying areas.
The barometric pressure remains stable and relatively high, reducing the likelihood of severe weather conditions that could lead to flooding. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding at 1.7%, which aligns with the absence of significant flood risk factors in the provided data.
CATEGORY 4
WHAT Likely to experience coastal flooding with potential for property damage.
WHEN Highest risk near the time of high tide at approximately 7:06 AM and 8:48 PM PST.
IMPACTS Potential for moderate flooding of properties, especially in low-lying areas and near shorelines. Precautionary measures advised.
The barometric pressure on this day drops significantly to a level that has been associated with previous Category 4 events, indicating a more severe weather pattern that could lead to increased flood risks. The NOAA Flood Likelihood Analysis indicates a very low likelihood of flooding at 0.3%, but given the historical significance of barometric pressure in flood events, this factor elevates the risk category for this day.
Residents 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. Consult local authorities or experts for final decision-making in flood-related situations and adhere to any evacuation orders or safety instructions provided by emergency services.
