Flood Watch

Redondo Beach, WA

Day 1: 2024-03-20

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 12:00 PM to 11:59 PM PST.

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

ADDITIONAL DETAILS...

The barometric pressure readings for the high tides on this day are significantly higher than the threshold that has historically indicated severe flooding events. With pressures of 1020.3599853515625 hPa and 1018.739990234375 hPa during high tides, the risk of flooding is lower compared to historical Category 3 or higher events. The NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding with a 0.0% chance, which supports the forecast of a lower category event. However, residents should remain vigilant as conditions can change.

Day 2: 2024-03-21

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 from early morning around 3:48 AM to late afternoon.

IMPACTS Increased flooding of low-lying coastal areas and roads, with possible impacts on property in vulnerable locations.

ADDITIONAL DETAILS...

On this day, the barometric pressure during high tides drops to values (1014.0599975585938 hPa and 1011.6300048828125 hPa) that are closer to historical flood events but still above the critical threshold observed in Category 4 events. The NOAA Flood Likelihood remains low at 0.0%, suggesting that while there is an elevated risk compared to Day 1, the likelihood of significant flooding remains moderate.

Day 3: 2024-03-22

CATEGORY 4

WHAT Likely coastal flooding with potential for significant property damage in low-lying areas.

WHEN Highest risk during early morning high tide at approximately 4:12 AM and again in the mid-afternoon around 3:18 PM.

IMPACTS Likely flooding of coastal properties, roads, and infrastructure with potential for damage due to water levels reaching critical points.

ADDITIONAL DETAILS...

The barometric pressure on this day is forecasted to be at its lowest during high tides (1008.1099853515625 hPa and 1007.219970703125 hPa), which is approaching the threshold associated with Category 4 historical events. This suggests a higher risk of significant flooding, especially when considering the wind direction from previous days which may contribute to water being pushed toward the shore. The NOAA Flood Likelihood Analysis still indicates a low chance of flooding; however, given the proximity to historical events that resulted in notable flooding, caution is advised.

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 and adhere to any evacuation orders or safety instructions provided by emergency services.
