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 04:00 AM to 05:00 AM PST and from 04:00 PM to 05:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The high tide at 04:12 AM on 2024-09-18 is expected to reach a height of approximately 18.83 feet with a barometric pressure of 1013.1 hPa. The high tide at 04:54 PM on the same day is expected to reach approximately 19.93 feet with a barometric pressure of 1015.6 hPa. Both events are characterized by relatively high barometric pressures, which reduce the likelihood of severe flooding. Wind speeds are low, ranging from 2 to 4 mph, and wind directions are generally from the north-northwest, which is not typically associated with severe coastal flooding in this region.

WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From 05:00 AM to 06:00 AM PST and from 05:00 PM to 06:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The high tide at 05:12 AM on 2024-09-19 is expected to reach a height of approximately 19.03 feet with a barometric pressure of 1017.9 hPa. The high tide at 05:24 PM on the same day is expected to reach approximately 20.05 feet with a barometric pressure of 1023.3 hPa. The higher barometric pressures indicate less severe weather conditions, reducing the likelihood of significant flooding despite the relatively high tide levels. Wind speeds remain low, ranging from 2 to 5 mph, with wind directions varying but generally not contributing significantly to flood risk.

WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From 06:00 AM to 07:00 AM PST and from 06:00 PM to 07:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The high tide at 06:12 AM on 2024-09-20 is expected to reach a height of approximately 19.06 feet with a barometric pressure of 1022.2 hPa. The high tide at 06:00 PM on the same day is expected to reach approximately 19.98 feet with a barometric pressure of 1022.2 hPa. The consistently high barometric pressures throughout the day suggest stable weather conditions, further reducing the likelihood of severe flooding despite the high tides. Wind speeds are slightly higher than previous days but still moderate, ranging from 3 to 6 mph, with wind directions generally from the south-southwest.
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 was conducted for each day based on provided data:
Barometric Pressure: All days show relatively high barometric pressures (above the critical threshold of ~992 hPa), indicating less severe weather conditions.
Tide Height: While tide heights are significant (ranging from ~18 ft to ~20 ft), they do not exceed historical extreme flood events (e.g., >21 ft).
Wind Direction and Speed: Wind speeds are low (ranging from ~2 mph to ~6 mph) and directions are not aligned with historical severe flood events.
NOAA High Tide Flooding Likelihood: NOAA's data indicates a low likelihood of flooding for all three days.
Based on these factors, all three days were categorized as Category 2 events, indicating minor coastal flooding potential without significant property damage risks.
