Flood Watch

Redondo Beach, WA

Day 1: 2024-07-30

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 8:00 AM to 10:00 AM PST.

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

ADDITIONAL DETAILS...

The barometric pressure is forecasted to be around 997.8 hPa during the high tide at 9:00 AM, which is higher than the threshold that historically indicates severe flooding (992.8 hPa). However, the tide height is expected to be significant at around 18.760 Ft at midnight, decreasing slightly throughout the day. The NOAA flood likelihood for this day is low, with a 0.0% chance of flooding and a distance to threshold of -2.01m. The wind direction is not provided but considering the pressure and tide data, there is a moderate risk of minor coastal flooding, especially during high tide times.

Day 2: 2024-07-31

CATEGORY 3

WHAT Potential for minor coastal flooding continues with similar conditions as Day 1.

WHEN From 3:00 PM to 5:00 PM PST.

IMPACTS Low-lying areas may experience minor flooding, with water potentially encroaching on parks, walkways, and roads near the shoreline.

ADDITIONAL DETAILS...

The barometric pressure remains slightly below the historical severe flooding threshold at around 996.9 hPa during high tide at 3:48 PM. The tide height is expected to be lower than on Day 1, with a peak of around 18.676 Ft at midnight, which decreases throughout the day. NOAA's flood likelihood remains low with a 0.0% chance of flooding and a distance to threshold of -2.38m. Without significant changes in weather conditions or wind direction data, the risk remains moderate for minor coastal flooding.

Day 3: 2024-08-01

CATEGORY 2

WHAT Coastal flooding risk decreases slightly due to increased barometric pressure.

WHEN Lowest risk compared to previous days; monitoring recommended during high tide times.

IMPACTS Minimal impact expected; however, localized issues may still occur in the most vulnerable areas.

ADDITIONAL DETAILS...

On this day, the barometric pressure increases to around 1000.1 hPa during high tides at both 11:00 AM and 4:36 PM, which is well above the historical threshold for severe flooding events. The tide height also shows a decreasing trend with a peak of around 17.999 Ft at midnight and gradually lowering throughout the day. NOAA's flood likelihood analysis indicates a low chance of flooding with a distance to threshold of -1.9m. Given these factors and without significant wind data suggesting otherwise, the risk of coastal flooding is lower than on previous days.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Residents and visitors 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. Stay informed about local tide schedules and adhere to any advisories issued by emergency management or local authorities.
