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 4:00 PM to 8:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold associated with previous flood events, suggesting less severe weather conditions. However, the high tide at 18:54 with a mean pressure MSL of 1003.5 hPa, although not as low as the most severe historical events, still presents a risk when combined with the predicted tide height. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the absence of extreme weather indicators.
CATEGORY 4
WHAT Coastal flooding likely. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN From 5:00 AM to 3:00 PM PST.
IMPACTS Likely flooding of roads, especially during high tide at 14:48. Some property damage possible in vulnerable areas.
The barometric pressure during the high tide at 14:48 is forecasted to be 994.8200073242188 hPa, which is closer to the threshold that has historically resulted in flooding events. The NOAA Flood Likelihood Analysis still indicates a low likelihood of flooding, but given the proximity to critical pressure levels and high tide heights, there is an increased risk compared to Day 1.
CATEGORY 5
WHAT Significant coastal flooding expected. Water levels may rise significantly, with potential for extensive property damage.
WHEN From early morning around high tide at 05:42 AM continuing through midday around high tide at 10:12 AM PST.
IMPACTS Significant flooding of residential and commercial properties expected. Road closures and disruptions to local infrastructure likely.
The barometric pressure during both high tides on this day is forecasted to be at the critical threshold of 992.8200073242188 hPa, which historically correlates with severe flood events. The NOAA Flood Likelihood Analysis maintains a low likelihood percentage; however, the combination of critical barometric pressure readings and high tide levels necessitates a higher category rating due to increased risk factors similar to past significant flood events.
Residents and businesses 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 and adhere to any evacuation orders or safety instructions provided by emergency services.
