Redondo Beach, WA
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 04:54 AM to 14:42 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
On 2024-09-27, the high tide at 04:54 AM is expected to reach a height of approximately 18.71 feet with a barometric pressure of 1013.11 hPa. The second high tide at 14:42 PM will reach around 18.92 feet with a barometric pressure of 1015.31 hPa. These conditions are similar to the Category 3 event on 12/27/2023 but with higher barometric pressure, reducing the likelihood of severe flooding. Wind speeds are relatively low, further minimizing the risk.
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 01:06 AM to 15:18 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
On 2024-09-28, the high tide at 01:06 AM is expected to reach a height of approximately 16.42 feet with a barometric pressure of 1015.75 hPa. The second high tide at 15:18 PM will reach around 18.96 feet with a barometric pressure of 1014.5 hPa. These conditions are similar to the Category 3 event on 12/27/2023 but with higher barometric pressure, reducing the likelihood of severe flooding. Wind speeds are relatively low, further minimizing the risk.
CATEGORY 3
WHAT Moderate coastal flooding expected. Possible inundation of up to 2 feet above ground level near shorelines and low-lying areas.
WHEN From 02:12 AM to 15:42 PM PST.
IMPACTS Moderate flooding of low-lying areas, parks, and roads. Some road closures possible.
On 2024-09-29, the high tide at 02:12 AM is expected to reach a height of approximately 16.75 feet with a barometric pressure of 1013.52 hPa. The second high tide at 15:42 PM will reach around 18.91 feet with a barometric pressure of 1008.61 hPa. These conditions are similar to the Category 4 event on 01/07/2022 but with slightly higher barometric pressure and lower wind speeds, reducing the likelihood of severe flooding but still warranting close monitoring.
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.
Step-by-step analysis indicates that while the tide heights are significant (18.71 ft and 18.92 ft), the relatively high barometric pressures (1013.11 hPa and 1015.31 hPa) suggest less severe weather conditions compared to historical severe flood events like those on 12/27/2022 or even the Category 4 event on 01/07/2022 where pressures were much lower (978.4 hPa and <=992.8 hPa respectively). Therefore, this day is categorized as Category 2.
Similar reasoning applies here; despite significant tide heights (16.42 ft and 18.96 ft), the higher barometric pressures (1015.75 hPa and 1014.5 hPa) reduce the likelihood of severe flooding compared to historical events with lower pressures and higher wind speeds.
The tide heights (16.75 ft and 18.91 ft) combined with a lower barometric pressure (1008.61 hPa) suggest a moderate risk for coastal flooding, similar to historical Category 3 events but not as severe as Category 4 or higher events due to slightly higher pressures and lower wind speeds.
By following this structured approach, we ensure that our flood potential assessments are accurate and based on historical data comparisons while prioritizing user safety through clear communication and precautionary advice.
