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 6:00 PM to 8:00 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 led to severe flooding events. With pressures of 1006.8 hPa and 1004.9 hPa during high tides, the likelihood of a major flood event is reduced. However, the tide height is not provided; thus, based on the NOAA's low flood likelihood prediction and the absence of critical tide height data, the risk remains categorized at a lower level. The wind direction is not specified in the provided data, which limits a comprehensive assessment.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in susceptible areas.
WHEN From 5:00 AM to 7:00 AM PST and again from 6:00 PM to 8:00 PM PST.
IMPACTS Moderate flooding of coastal areas, with some roads potentially becoming impassable. Property damage is unlikely but possible in very low-lying regions.
On this day, the barometric pressure readings during high tides are closer to historical flood event thresholds, with pressures of 1003.5 hPa and 1000.6 hPa. These readings, paired with unspecified high tide levels that could potentially be above the critical mark, increase the risk category slightly compared to Day 1. The NOAA's flood likelihood remains low, which tempers the overall risk assessment.
CATEGORY 4
WHAT Likely coastal flooding with water levels expected to reach up to 2 feet above ground in vulnerable areas.
WHEN From 5:45 AM to 7:45 AM PST and again from 7:30 PM to 9:30 PM PST.
IMPACTS Likely flooding of coastal properties and infrastructure with a possibility of minor property damage due to water intrusion in low-lying regions.
The barometric pressure readings for Day 3's high tides are at a concerning level of approximately 999.8 hPa, which is below the historical threshold for significant flooding events. This data point is critical as it suggests a greater potential for severe weather conditions that could lead to flooding, especially if accompanied by high tide levels over the critical mark of 21 feet. The NOAA's flood likelihood data indicates a low chance of flooding; however, given the historical significance of barometric pressure in flood events, this day's risk is elevated compared to the previous days.
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 adhere to any evacuation orders or safety instructions provided by emergency services.
