Flood Watch

Redondo Beach, WA

Day 1: 2024-05-08

CATEGORY 2

WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

WHEN From 3:30 AM to 4:30 AM PST and from 5:30 PM to 6:30 PM PST.

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

ADDITIONAL DETAILS...

The barometric pressure during the high tides of Day 1 is significantly higher than the threshold that has historically led to severe flooding events. The tide height is not reaching the levels seen in past Category 4 or higher events, and NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this day. Wind direction data is not provided, but given the other factors, the risk remains categorized at a lower level.

Day 2: 2024-05-09

CATEGORY 3

WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.

WHEN Highest risk near the time of high tide at approximately 6:54 PM PST.

IMPACTS Increased flooding of low-lying areas and roads, with some property damage possible. Residents should be prepared for potential road closures and minor disruptions.

ADDITIONAL DETAILS...

On Day 2, the barometric pressure during the high tide is closer to historical events that have resulted in Category 4 flood events. However, the tide height is still below the thresholds seen in those past events, and NOAA's Flood Likelihood Analysis continues to indicate a low likelihood of flooding. Without wind direction data, we rely more heavily on barometric pressure and tide height, which suggests a slightly elevated risk compared to Day 1.

Day 3: 2024-05-10

CATEGORY 4

WHAT Likely coastal flooding with potential for significant property damage in vulnerable areas.

WHEN Highest risk near the time of high tide at approximately 5:00 AM PST and again around 2:48 PM PST.

IMPACTS Likely flooding of properties, especially in low-lying areas, with road closures and disruptions to daily activities. Residents should prepare for significant impacts and follow local authority guidance.

ADDITIONAL DETAILS...

Day 3 presents a more concerning scenario with barometric pressures during high tides that are similar to those seen in past Category 4 flood events. The tide heights are also notably higher than on previous days, further increasing the risk. Although NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding, the proximity of pressure readings to critical thresholds warrants a higher category rating for this day.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
