Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 11:00 AM to 1:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be 1006.7 hPa during the high tide at 11:48 AM, which is higher than the threshold that has historically led to significant flooding events. However, the tide height is not provided in the user data. Based on historical events, a tide height over 16 Ft combined with this pressure could increase flood risks. The NOAA Flood Likelihood for this day is low, which suggests that while there may be minor coastal flooding due to high tide, it is unlikely to be severe.
CATEGORY 4
WHAT Coastal flooding likely. Potential for up to 1 foot of inundation above ground level in low-lying areas near the shoreline.
WHEN Highest risk near the times of high tide at 7:18 AM and again at 1:42 PM PST.
IMPACTS Flooding of coastal properties, roads, and basements in low-lying areas. Some road closures and minor property damage possible.
The barometric pressure is forecasted to be around 1001.3 hPa to 1002.4 hPa during high tides, which is closer to historical events that have caused flooding but still above the critical threshold of 992.8 hPa. The NOAA Flood Likelihood remains low; however, given the lower pressures expected compared to Day 1, there is an increased risk of flooding, especially if wind direction and speed are conducive to pushing water onshore.
CATEGORY 5
WHAT Significant coastal flooding expected with property damage likely. Inundation levels may reach or exceed 2 feet above ground level in vulnerable areas.
WHEN Highest risk near the time of high tide at 8:48 AM PST.
IMPACTS Significant flooding of coastal properties and infrastructure. Road closures likely with moderate property damage possible.
The barometric pressure is forecasted to drop to around 997.5 hPa during high tide, which is below the historical threshold for significant flooding events. The NOAA Flood Likelihood data indicates a low likelihood; however, given the proximity of the pressure readings to critical levels observed during past flood events, there is a heightened risk for significant flooding impacts on this day.
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 in flood-related situations and adhere to any evacuation orders or safety instructions provided by emergency services.
