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 2:00 PM to 5:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be around 1014 hPa during the high tide, which is significantly higher than the threshold associated with previous flood events. The tide height is not expected to exceed the critical mark of 21 feet that has historically led to severe flooding. Wind direction from the north at low speeds is not conducive to pushing water ashore aggressively. NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this date.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN Highest risk near the time of high tide at approximately 12:24 PM PST.
IMPACTS Increased flooding of coastal and low-lying areas, with possible impacts on property and infrastructure. Some roadways may become impassable.
The barometric pressure is lower on this day, around 1007 hPa during high tide, which is closer to the threshold that has been associated with previous flood events. The tide height is still below the critical level seen in Category 4 or higher events but is within the range that has caused concern in the past. The wind direction information is not provided, but given the lower barometric pressure and NOAA's low likelihood of flooding, there is an elevated risk compared to Day 1.
CATEGORY 3
WHAT Continued elevated risk of coastal flooding with potential for water levels reaching similar heights as Day 2.
WHEN Highest risk near the time of high tide at approximately 1:36 PM PST.
IMPACTS Similar impacts as Day 2 are expected, with coastal and low-lying area flooding and potential road closures.
Barometric pressure remains lower than normal at approximately 1007 hPa during high tide, indicating a persistent system that could contribute to elevated water levels. The tide height does not reach the severe thresholds noted in historical Category 4 or higher events but remains a concern due to sustained lower pressure. Without specific wind direction data, we rely on barometric pressure and tide levels to maintain an elevated risk assessment.
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.
