Redondo Beach, WA
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 3:30 AM to 5:00 AM PST and from 4:30 PM to 6:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure readings for the high tides on this day are significantly higher than the threshold that has historically led to severe flooding events. However, the tide heights are approaching levels that have previously resulted in minor coastal flooding. The NOAA flood likelihood is low, which aligns with the pressure data indicating a less severe event. Wind direction is not provided but would be considered if it were from the W/NW.
CATEGORY 4
WHAT Coastal flooding likely, with potential for some property damage in vulnerable areas.
WHEN From 12:00 PM to 2:00 PM PST and from 5:30 PM to 7:30 PM PST.
IMPACTS Flooding of properties especially in low-lying areas, with possible damage. Road closures and disruptions to daily activities likely.
The barometric pressure is nearing the critical threshold of 992.8 hPa during high tides, which historically correlates with more significant flooding events. The tide heights are also elevated, further increasing the risk. The NOAA flood likelihood remains low, but given the pressure and tide data, a higher category is warranted.
CATEGORY 4
WHAT Coastal flooding likely, similar to Day 2's conditions with potential for property damage.
WHEN From 3:00 AM to 5:00 AM PST and from 1:00 PM to 3:00 PM PST.
IMPACTS Continued risk of property damage in low-lying coastal areas. Persistent road closures and impact on infrastructure possible.
Barometric pressure remains just below the critical threshold during high tides, maintaining an elevated risk of flooding. Tide heights are still significant but do not exceed the highest historical levels associated with Category 5 events. The NOAA flood likelihood is low; however, the proximity of pressure readings to critical levels justifies a Category 4 rating.
Residents 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. Consult local authorities or experts for final decision-making in flood-related situations.
