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 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 readings for the high tides on this day are significantly higher than the threshold that has historically indicated severe flooding events. With pressures well above 1000 hPa, the risk of flooding due to atmospheric conditions is low. The tide data shows high tide levels, but without the corresponding low pressure, the risk remains minor. The NOAA flood likelihood for this day is also low, with a 0.0% likelihood of flooding, which supports the lower category rating.
CATEGORY 2
WHAT Minimal risk of coastal flooding. No significant impact expected.
WHEN Highest risk around high tides, particularly in the afternoon and evening.
IMPACTS No significant impacts anticipated. Normal high tide conditions with no extraordinary flooding expected.
Similar to Day 1, the barometric pressure remains high during the predicted high tides for Day 2, indicating stable atmospheric conditions that are not conducive to severe flooding. The NOAA flood likelihood remains at 0.0%, suggesting a continued low risk of flooding events.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to lower barometric pressure and high tides.
WHEN Potential for higher water levels during morning and midday high tides.
IMPACTS Possible minor flooding in susceptible coastal areas and low-lying regions. Increased water levels may lead to minor disruptions.
On Day 3, the barometric pressure drops closer to levels that have been associated with previous flood events, although it still remains above the critical threshold of 992.8 hPa observed in historical Category 4 events. The tide height is also elevated, which when combined with lower pressure could result in a slightly higher risk of flooding compared to the previous days. The NOAA flood likelihood data is not indicating an increased risk; however, given the lower pressure readings and historical comparisons, a Category 3 rating is warranted as a precautionary measure.
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. Stay informed through local news sources and official channels for any updates on weather conditions and potential emergency instructions.
