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 11:00 AM to 2:00 PM 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 12:30 PM with a mean pressure MSL of 1033.25 hPa is well above the threshold that has historically indicated flooding, reducing the likelihood of a severe flood event. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, with a distance to threshold at -2.32m, which supports the assessment of a lower category flood potential.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for up to 1 foot of inundation above ground level in vulnerable areas.
WHEN Highest risk near the time of high tide at 4:30 AM and again around midday.
IMPACTS Increased flooding of low-lying coastal areas and roads, with possible impacts to property in vulnerable locations.
The barometric pressure on this day is lower than on Day 1, with a mean pressure MSL of 1027.020 hPa during the high tide at 4:30 AM, which brings it closer to historical flood event pressures. However, it remains above the critical threshold observed in past Category 4 or higher events. NOAA's Flood Likelihood Analysis still indicates a low likelihood of flooding, which suggests that while there may be an increased risk compared to Day 1, it is not expected to reach severe levels.
CATEGORY 4
WHAT Likely coastal flooding with potential for significant property damage. Inundation levels may reach or exceed 2 feet above ground level in some areas.
WHEN Highest risk during high tides at approximately 2:36 PM and again at around 7:18 PM.
IMPACTS Likely flooding of coastal properties and infrastructure. Road closures and disruptions to daily activities are possible.
On Day 3, the barometric pressure drops to a mean pressure MSL of 1022.0 hPa during both high tides, which is closer to the pressures observed during historical Category 4 events. This lower pressure combined with high tides increases the risk of significant flooding. The NOAA Flood Likelihood Analysis does not indicate an increased likelihood for this date; however, given the proximity to historical event pressures and high tide levels, there is a heightened concern for potential flooding impacts.
Residents and businesses near the shore 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.
