Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
*WHEN From 6:00 PM to 9:00 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 associated with past Category 5 events, suggesting less severe weather conditions. However, the tide height is approaching levels that have previously caused flooding, particularly during the high tide at 6:18 PM with a pressure of 1001.82 hPa and at 8:48 PM with a pressure of 1007.48 hPa. The wind speed from the weather data is moderate and not indicative of severe storm conditions that could exacerbate flooding risks.
CATEGORY 2
WHAT Low risk of coastal flooding.
WHEN The risk is present throughout the day due to high tides but is not expected to cause significant impact.
IMPACTS No significant impacts expected. Normal high tide conditions with no immediate threat of flooding.
The barometric pressure on Day 2 remains above the critical threshold, and while there are high tides expected, they are not reaching the levels that have historically resulted in flooding. The highest tide at 11:48 AM has a corresponding pressure well above the threshold for major flood events.
CATEGORY 4
WHAT Likely to experience coastal flooding with potential for property damage.
WHEN Highest risk during high tides, particularly around midday and late afternoon.
IMPACTS Potential for flooding of properties, especially in low-lying areas. Risk of road closures and disruption to local infrastructure.
On Day 3, the barometric pressure drops closer to the threshold seen in historical Category 4 events, which increases the risk of flooding despite being above the Category 5 reference point. The tide heights during high tides at 12:54 PM and at 5:12 PM are also notably high, which when combined with lowering barometric pressure could result in significant coastal flooding.
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 in flood-related situations and adhere to any evacuation orders or safety advisories issued by them.
