Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 6:00 AM to 9:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold that typically indicates severe weather conditions and potential flooding. The high tide at 07:24 with a mean pressure MSL of 1028.449951171875 hPa suggests a lower likelihood of flooding despite the high tide level. The weather data indicates overcast conditions with moderate rain, which may contribute to localized pooling but is unlikely to cause significant flooding due to the high atmospheric pressure.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN From 6:30 AM to 10:00 AM PST.
IMPACTS Increased risk of flooding in low-lying areas and roads near the shoreline. Some property damage possible, particularly in vulnerable structures.
The barometric pressure is lower than on Day 1, nearing the threshold that increases the likelihood of flooding. The high tide at 07:48 with a mean pressure MSL of 1019.4600219726562 hPa is closer to historical Category 3 events. Weather conditions show heavy snow with thunder, which could contribute to rapid accumulation and runoff, exacerbating flood risks. The NOAA flood likelihood is low; however, the proximity to the threshold warrants caution.
CATEGORY 4
WHAT Likely coastal flooding with potential for significant property damage in some areas.
WHEN From 7:00 AM to 10:30 AM PST and again from 9:30 PM to midnight PST.
IMPACTS Flooding of coastal properties and infrastructure likely. Road closures and disruptions to daily activities expected.
The barometric pressure on Day 3 is forecasted to be at a critical low (1010.8099975585938 hPa) during both high tides, which is similar to historical Category 4 events. This greatly increases the risk of significant flooding, especially when combined with the expected heavy snow from the previous day that could contribute to runoff and elevated water levels. The wind direction from the south-southeast may push additional water towards the coast, further increasing flood risks.
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 and adhere to any evacuation orders or safety instructions provided by emergency services.
