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 2:00 AM to 5:00 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 indicates severe weather conditions and potential flooding. The high tide at 03:00 with a mean pressure MSL of 1004.5599975585938 hPa is not indicative of a severe flood risk, especially when compared to historical events that had lower pressures and higher tide levels. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the current data assessment.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN Highest risk during high tides, particularly around 3:18 AM and again at approximately 4:00 PM PST.
IMPACTS Increased flooding of coastal areas, parks, and roads with potential for minor property damage in vulnerable locations.
The barometric pressure readings for the high tides on this day are closer to historical events that have resulted in flooding, particularly the second high tide at 16:00 with a mean pressure MSL of 1002.260009765625 hPa. While still above the critical threshold, it warrants closer monitoring due to its proximity to historical Category 3 events. NOAA's Flood Likelihood Analysis maintains a low likelihood rating for this date, but the proximity of the pressure readings to concerning levels justifies an elevated category rating.
CATEGORY 4
WHAT Likely coastal flooding with potential for significant property damage in low-lying areas.
WHEN High risk during high tides, especially around 3:36 AM and again at approximately 4:42 PM PST.
IMPACTS Flooding of coastal properties, roads, and infrastructure is likely. Residents should prepare for possible evacuations and protect property where possible.
The barometric pressure readings for both high tides on this day are very close to or below the threshold associated with historical Category 4 events. The second high tide at 16:42 with a mean pressure MSL of 1001.969970703125 hPa is particularly concerning as it approaches conditions seen in past significant flood events. Although NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding, the combination of high tide levels and low barometric pressure necessitates a higher category rating due to the increased risk these conditions present based on historical data.
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 follow any evacuation orders or safety instructions provided by emergency services.
