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 5:00 AM to 7:00 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 has historically led to severe flooding, suggesting less severe weather conditions for this event. The high tide at 05:54 with a mean pressure MSL of 1019.0 hPa does not approach the critical lower pressure levels seen in past Category 4 or higher events. However, the NOAA Flood Likelihood Analysis indicates a low likelihood of flooding, which aligns with the Category 3 prediction based on historical data comparison.
CATEGORY 2
WHAT Coastal conditions are expected to be relatively stable with a very low chance of minor flooding.
WHEN The risk is lowest throughout the day due to higher barometric pressure.
IMPACTS No significant impacts expected. Normal tidal conditions with no anticipated disruption.
The barometric pressure on this day is forecasted to be even higher than on Day 1, which correlates with a lower risk of flooding. The high tide at 06:24 with a mean pressure MSL of 1017.8 hPa is well above the critical threshold for severe flooding events. The NOAA Flood Likelihood Analysis also indicates a low likelihood of flooding, supporting the Category 2 prediction.
CATEGORY 6
WHAT Major coastal flooding expected. Potential for significant inundation and property damage near shorelines and low-lying areas.
WHEN Highest risk from early morning around high tide at 06:54 AM through late evening.
IMPACTS Significant flooding of residential and commercial areas near the coast. Road closures and disruptions to infrastructure likely. Potential for property damage.
On this day, the barometric pressure drops significantly to a mean pressure MSL of 1003.9 hPa during both high tides, which is much closer to the critical threshold observed in historical Category 4 and Category 5 events. This low pressure, combined with NOAA's high likelihood of flooding at 10.1%, indicates a substantial risk for major flooding events similar to or exceeding the Category 4 event on 01/07/2022.
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.
