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 6:00 PM 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. However, the high tide at 17:42 with a mean pressure MSL of 1005.3200073242188 hPa, while not as low as the threshold, still warrants attention due to its proximity to historical Category 3 events. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the absence of extreme weather indicators in the provided weather data.
CATEGORY 4
WHAT Coastal flooding likely. Inundation of up to 1 foot above ground level in some shorelines and low-lying areas.
WHEN From 5:00 PM to 7:00 PM PST.
IMPACTS Flooding of coastal areas, parks, and roads near the shore. Road closures and minor property damage possible.
The barometric pressure at the time of high tide is forecasted to be 999.1099853515625 hPa, which is closer to the threshold that increases the likelihood of flooding. The high tide at 18:12 is within the range that has historically led to Category 4 events. The NOAA Flood Likelihood Analysis maintains a low likelihood for this date; however, the pressure data suggests a greater risk than indicated by NOAA's analysis.
CATEGORY 5
WHAT Significant coastal flooding expected. Inundation may exceed 1 foot above ground level in many shorelines and low-lying areas.
WHEN From 4:00 AM to 10:00 AM PST.
IMPACTS Significant flooding of coastal properties and infrastructure. Road closures and property damage are likely.
The barometric pressure during high tides is forecasted to be below the critical threshold (997.9099731445312 hPa and 997.4600219726562 hPa), indicating a strong possibility of severe weather conditions conducive to flooding. This situation closely resembles the historical Category 5 event on 12/27/2022, with similar pressure readings but slightly lower tide heights. Despite NOAA's low likelihood prediction for this date, the combination of extremely low barometric pressure and high tide levels necessitates a higher flood category prediction.
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.
