WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 3:00 PM to 7:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure during the high tide at 18:48 is 1017.2 hPa, which is significantly higher than the threshold that indicates severe weather conditions and potential flooding. The tide height at this time is not provided, but given the low likelihood of flooding from NOAA's data for this date and the high barometric pressure, the risk is categorized as a Category 3 event. This is similar to the historical event on 12/27/2023, which had a lower barometric pressure but was still categorized as a Category 3 event due to the absence of other severe weather indicators.
CATEGORY 4
WHAT Coastal flooding likely. Inundation of up to 1 foot above ground level in low-lying areas near shorelines.
WHEN From 3:00 AM to 7:00 AM PST and again from 6:30 PM to 9:30 PM PST.
IMPACTS Flooding of parks, roads, and basements in vulnerable areas. Some road closures expected.
The barometric pressure during the high tide at 19:30 is 1009.0 hPa, which is closer to the threshold that indicates more severe weather conditions and potential flooding. The tide height at this time is not provided, but given the lower barometric pressure and the historical comparison with events that had similar or lower pressures, there is an increased risk of flooding. The risk is categorized as a Category 4 event due to the lower barometric pressure and its proximity to historical events that resulted in significant flooding.
CATEGORY 5
WHAT Significant coastal flooding expected. Inundation likely more than 1 foot above ground level in many shorelines and low-lying areas.
WHEN From 7:00 PM to 10:00 PM PST.
IMPACTS Widespread flooding of coastal areas, including roads, basements, and potentially first floors of unprotected structures. Numerous road closures and property damage likely.
The barometric pressure during the high tide at 20:18 is significantly low at 1003.8 hPa, which is well below the threshold indicating severe weather conditions and potential for major flooding. This pressure reading is similar to historical Category 5 events that resulted in significant property damage due to flooding. The risk on this day is categorized as a Category 5 event due to the extremely low barometric pressure combined with high tide levels, which are known factors contributing to severe flood conditions in Redondo Beach, WA.
