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 forecasted to be around 999.4 hPa during the high tide at 5:30 PM, which is higher than the threshold that historically indicates severe flooding (992.8 hPa). However, the tide height is expected to be significant, and when combined with the northwest winds, there could be minor coastal flooding. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the absence of extreme weather conditions suggested by the barometric pressure data.
CATEGORY 3
WHAT Continued minor coastal flooding potential with similar conditions as Day 1.
WHEN From 4:00 PM to 8:00 PM PST.
IMPACTS Potential for minor and localized flooding in susceptible areas, especially during high tide.
The barometric pressure remains relatively stable at around 998.0 hPa during the high tide at 6:06 PM, which does not suggest a major storm system. The tide height is not expected to reach the levels seen in historical Category 4 or 5 events. Wind direction and NOAA's low flood likelihood support the assessment of a Category 3 flood event for this day as well.
CATEGORY 4
WHAT Elevated risk of coastal flooding due to higher tides and slightly lower barometric pressure.
WHEN From 5:00 PM to 9:00 PM PST.
IMPACTS Increased likelihood of flooding in low-lying coastal areas and roads, with possible property damage in vulnerable locations.
On this day, the barometric pressure drops closer to the critical threshold at approximately 994.8 hPa during the high tide at 6:42 PM. This lower pressure, combined with high tides and wind direction from the northwest, increases the risk of coastal flooding compared to the previous days. While still not reaching the historical Category 5 event criteria, there is a noticeable increase in risk warranting a Category 4 classification.
Residents and visitors 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 regarding flood-related situations and adhere to any evacuation orders or safety instructions provided by emergency services.
