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 10:00 PM to 11:59 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 flooding events, suggesting less severe weather conditions. The high tide at 22:18 with a mean pressure MSL of 1014.0499877929688 hPa is not indicative of a major flood risk when compared to historical data. Wind direction from the west, as indicated in the current weather data, could contribute to water levels but is not expected to cause significant flooding due to the relatively high barometric pressure.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN From early morning around 07:54 AM to late evening around 11:59 PM PST.
IMPACTS Increased risk of flooding in low-lying areas and roads near the shoreline. Some property damage possible, particularly in vulnerable structures.
The barometric pressure is lower than on Day 1, nearing the threshold that has historically led to more significant flooding events. The high tide at 23:12 with a mean pressure MSL of 1009.989990234375 hPa is closer to conditions seen during previous Category 3 events. The wind direction is not specified but should be monitored for changes that could influence tide levels.
CATEGORY 4
WHAT Likely flooding with potential for significant property damage in coastal areas.
WHEN Highest risk during high tide at approximately 09:12 AM PST.
IMPACTS Likely flooding of coastal properties, roads, and infrastructure. Preparations should be made for potential evacuations and road closures.
The barometric pressure on Day 3 drops further, which is a strong indicator of severe weather conditions and potential flooding, especially when paired with high tide levels over 21 ft. The high tide at 09:12 AM with a mean pressure MSL of 1006.8699951171875 hPa is within the range that has historically led to Category 4 events. This forecast is also supported by NOAA's low likelihood percent for flooding, which may not fully capture the imminent risk due to the significantly lower barometric pressure and high tide levels expected.
Residents and businesses 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 and follow any evacuation orders or safety instructions provided by emergency services.
