Flood Watch

Redondo Beach, WA

Day 1: 2024-04-27

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 5:00 PM to 8:30 PM PST.

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

ADDITIONAL DETAILS...

The barometric pressure is significantly higher than the threshold associated with past flooding events, suggesting less severe weather conditions. The high tide at 5:30 PM is not expected to reach levels that have historically caused flooding, despite being relatively high. The wind direction is from the south, which may not significantly contribute to storm surge in this region. Comparing with historical data, especially the event on 12/17/2022, the risk of high-tide flooding is lower due to the absence of extremely low barometric pressure and less severe predicted weather conditions.

Day 2: 2024-04-28

CATEGORY 2

WHAT Potential for minor coastal flooding near high tide.

WHEN Highest risk near the high tide at 6:00 AM and again around the high tide at 9:12 PM PST.

IMPACTS Low-lying areas and parks may experience minor overflow; precautionary measures advised for waterfront properties.

ADDITIONAL DETAILS...

The barometric pressure remains well above the critical threshold, reducing the likelihood of significant flooding despite higher tide levels. The wind direction is not specified but given the pressure readings and lack of extreme weather indicators, major flooding is not anticipated. The NOAA flood likelihood remains low for this date, supporting the assessment of a Category 2 flood event risk.

Day 3: 2024-04-29

CATEGORY 3

WHAT Elevated risk of coastal flooding due to higher tides and lower barometric pressure.

WHEN High tide events at approximately 4:54 PM and again at 10:54 PM PST pose the greatest risk.

IMPACTS Increased potential for minor property damage in low-lying coastal areas. Residents should monitor conditions and be prepared for possible action.

ADDITIONAL DETAILS...

On this day, the barometric pressure drops closer to levels associated with previous flood events, although it remains above the critical threshold. The high tides are also forecasted to be higher than on previous days, which when combined with lower pressure could result in more significant tidal surges. The NOAA flood likelihood analysis indicates a low chance of flooding; however, given the lower barometric pressure and higher tides, there is a slightly increased risk compared to previous days. This analysis suggests a Category 3 flood event risk due to these compounding factors.

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.
