Flood Watch

Redondo Beach, WA

Day 1: 2024-05-15

CATEGORY 3

WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.

WHEN From 9:00 AM to 6:00 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 that indicates severe weather conditions and potential flooding. However, the high tide at 09:54 with a mean pressure MSL of 1011.0 hPa, although not as low as historical flooding events, still warrants attention due to the proximity to the threshold. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this day, which aligns with the absence of critical barometric pressure readings that would suggest a higher risk. The wind direction is not provided but would be a contributing factor if from the W/NW.

Day 2: 2024-05-16

CATEGORY 2

WHAT No significant coastal flooding expected.

WHEN Throughout the day.

IMPACTS No significant impacts anticipated.

ADDITIONAL DETAILS...

No high tide or barometric pressure data provided for this date. However, based on the NOAA Flood Likelihood Analysis indicating a low likelihood of flooding and the absence of any concerning weather data, it is assessed that there is no significant risk of flooding on this day.

Day 3: 2024-05-17

CATEGORY 4

WHAT Coastal flooding likely with potential for property damage in vulnerable areas.

WHEN Highest risk near high tides at 00:48 and 12:54 PST.

IMPACTS Flooding of properties in low-lying coastal areas, road closures, and disruptions to daily activities in affected zones.

ADDITIONAL DETAILS...

The barometric pressure readings for the high tides on this date are notably lower than on previous days, with readings nearing the threshold that historically indicates increased flood risk. The high tide levels are not as extreme as the Category 5 event from historical data but are still significant enough to warrant concern when paired with these lower pressure readings. The NOAA Flood Likelihood Analysis maintains a low likelihood percentage; however, given the proximity to historical events that resulted in actual flooding, it is prudent to forecast a higher risk category for this date.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Residents and businesses in Redondo Beach 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.
