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 4:00 PM to 6:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure readings for the high tides on this day are significantly higher than the threshold that has historically indicated severe flooding events. The tide height is also below the levels seen in past Category 4 or higher events. However, given the high tide at 17:12 with a mean pressure MSL of 1007.6799926757812 hPa, there is a slight risk of minor coastal flooding, especially in susceptible areas. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the other data points to suggest a Category 2 event.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for up to 1 foot of inundation above ground level in vulnerable areas.
WHEN From 5:00 PM to 7:00 PM PST.
IMPACTS Moderate flooding of low-lying areas and roads near the shoreline. Some road closures and minor property damage possible.
On this day, the barometric pressure at the time of high tide is slightly lower than on Day 1, indicating a marginally higher risk of flooding. The NOAA Flood Likelihood Analysis still indicates a low likelihood, but given the proximity to historical Category 3 conditions, particularly with a high tide at 17:42 and mean pressure MSL of 1005.1099853515625 hPa, there is an elevated risk warranting a Category 3 classification.
CATEGORY 4
WHAT Likely coastal flooding with potential for significant property damage in areas near the shoreline.
WHEN From 5:00 PM to 7:30 PM PST.
IMPACTS Likely flooding of roads and properties near the coast. Preparations should be made for potential road closures and property protection measures.
The barometric pressure on this day drops closer to the threshold associated with more severe flood events, particularly with a high tide at 18:12 and mean pressure MSL of 1000.739990234375 hPa. This pressure is closer to historical Category 4 events, and when combined with the high tide prediction, suggests a strong likelihood of flooding similar to past Category 4 events. The NOAA Flood Likelihood Analysis maintains a low likelihood rating; however, given the significant drop in barometric pressure and historical comparisons, a Category 4 classification is warranted for this day.
Residents and businesses near the shoreline 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.
