Flood Watch

Redondo Beach, WA

Day 1: 2024-09-09

CATEGORY 2

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

*WHEN From 07:00 AM to 09:00 AM PST.

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

ADDITIONAL DETAILS...

The high tide at 07:48 AM on 2024-09-09 is expected to reach 17.635 feet with a barometric pressure of approximately 1009.5 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of severe flooding. Wind speeds are relatively low at around 4 mph from the WSW, which is not expected to significantly exacerbate flooding conditions. Historical data indicates that similar conditions have resulted in minor flooding events.

Day 2: 2024-09-10

CATEGORY 2

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

WHEN From 04:30 AM to 06:30 AM PST.

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

ADDITIONAL DETAILS...

The high tide at 04:48 AM on 2024-09-10 is expected to reach 13.403 feet with a barometric pressure of approximately 1010.9 hPa. This pressure is well above the critical threshold, indicating a lower risk of severe flooding. Wind speeds are around 6 mph from the SSW, which is not expected to significantly impact flooding conditions. Historical data suggests that similar conditions have resulted in minor flooding events.

Day 3: 2024-09-11

CATEGORY 2

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

WHEN From 12:00 PM to 02:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 12:12 PM on 2024-09-11 is expected to reach approximately 17.300 feet with a barometric pressure of around 1014.2 hPa. This pressure is significantly higher than the critical threshold, reducing the likelihood of severe flooding. Wind speeds are relatively low at around 7 mph from the SSW, which is not expected to significantly exacerbate flooding conditions. Historical data indicates that similar conditions have resulted in minor flooding events.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You 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.


Analysis Summary:

Based on the provided data and historical comparisons: 1. Barometric Pressure: All three days show barometric pressures well above the critical threshold of 992.8 hPa. 2. Tide Heights: The highest tide heights are around or below the significant flood event thresholds observed in historical data. 3. Wind Direction and Speed: Wind speeds are relatively low and not from directions that historically exacerbate flooding. 4. NOAA Flood Likelihood: NOAA's analysis indicates a low likelihood of flooding for all three days.

Given these factors, all three days are categorized as Category 2 events, indicating minor coastal flooding with limited impacts primarily in low-lying areas near shorelines.
