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 AM to 9:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The current barometric pressure is above the threshold that historically indicates severe flooding, and the tide height is not reaching the levels seen in past Category 4 or higher events. However, the high tide at 8:48 AM with a pressure of 996.760009765625 hPa, while not below the critical threshold of 992.8 hPa, still warrants attention due to its proximity to this value. The wind direction is not provided but should be monitored if it comes from the W/NW as it can push water ashore. The NOAA Flood Likelihood for this day is low, which aligns with the Category 3 assessment.
CATEGORY 3
WHAT Continued minor coastal flooding potential with similar conditions as Day 1.
WHEN From 3:00 PM to 6:00 PM PST.
IMPACTS Persistent minor flooding in vulnerable areas, with potential for some property impact in especially low-lying regions.
The barometric pressure is slightly lower than on Day 1, with a high tide at 4:00 PM showing a mean pressure MSL of 993.8300170898438 hPa. This is closer to the critical threshold but still above it. The NOAA Flood Likelihood remains low, suggesting that while conditions are worth monitoring, significant flooding is not anticipated.
CATEGORY 4
WHAT Elevated risk of coastal flooding due to lower barometric pressure and high tides.
WHEN From 3:30 PM to 6:30 PM PST.
IMPACTS Likely flooding of coastal areas with some property damage possible, especially in low-lying regions and areas with poor drainage.
On Day 3, the barometric pressure drops significantly to around 990.97998046875 hPa during high tides at both 10:54 AM and 4:42 PM, which is below the critical threshold and has historically been associated with more severe flooding events. While NOAA's Flood Likelihood remains low, the combination of lower pressure and high tides warrants a higher category rating due to increased risk compared to 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. Stay informed about the latest weather updates and local emergency management recommendations.
