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 6:00 AM to 9:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold that indicates severe weather conditions and potential flooding. The high tide at 07:24 has a mean pressure MSL of 1028.43994140625 hPa, which is well above the historical event thresholds that led to more severe flooding. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, with a 0.0% likelihood percent and a distance to the flood threshold of -2.02m. Weather data shows overcast conditions with light rain, which may contribute to minor flooding in susceptible areas.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to high tide and decreasing barometric pressure. Inundation up to 1 foot above ground level possible in some areas.
WHEN From 6:00 AM to 10:00 AM PST, with another period of concern from 8:00 PM to midnight.
IMPACTS Moderate flooding of coastal areas, parks, and roads near the shoreline. Some road closures and minor property damage may occur.
The barometric pressure during the high tide at 07:48 is at 1019.030029296875 hPa, which is closer to historical events that have caused flooding but still above the critical threshold. The NOAA Flood Likelihood Analysis maintains a low likelihood for this date as well. However, given the lower barometric pressure compared to Day 1 and the proximity to historical Category 3 events, there is an elevated risk for flooding, especially considering the predicted heavy snow and moderate rain in the weather forecast.
CATEGORY 4
WHAT Likely coastal flooding due to high tide and significantly lower barometric pressure. Potential for property damage in low-lying coastal areas.
WHEN Highest risk from 7:00 AM to 11:00 AM PST and again from 9:00 PM to midnight.
IMPACTS Likely flooding of coastal properties, roads, and infrastructure with potential for property damage. Preparations for flood mitigation measures are advised.
On this day, the barometric pressure during both high tides is at a concerning level of 1010.7999877929688 hPa, which is very close to historical Category 4 events that resulted in significant flooding and property damage. The NOAA Flood Likelihood Analysis still indicates a low likelihood percent; however, given the proximity of the pressure readings to past events and the forecasted patchy light snow turning into heavier snowfall throughout the day, there is an increased risk for substantial flooding impacts.
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. Consult local authorities or experts for final decision-making in flood-related situations and follow any evacuation orders or safety instructions provided by emergency services.
