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 3:00 AM to 4:00 AM PST and from 5:30 PM to 6:30 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 flood events. With pressures well above 1040 hPa, the risk of flooding due to atmospheric conditions is low despite the occurrence of high tides. The NOAA Flood Likelihood Analysis also indicates a low likelihood of flooding for this date, with a likelihood percent of 0.0%. These factors combined with the historical data suggest a minor risk for coastal flooding.
CATEGORY 3
WHAT Elevated risk of coastal flooding, particularly during high tide periods. Potential for water levels to reach up to 1 foot above ground in susceptible areas.
WHEN From 4:00 AM to 5:00 AM PST and around 1:30 PM PST.
IMPACTS Increased flooding of low-lying coastal areas, parks, and roads near the shoreline. Some road closures may be necessary.
The barometric pressure on this day shows a slight decrease compared to Day 1 but remains high at around 1040 hPa during the first high tide and slightly lower at approximately 1040 hPa during the second high tide. Although these values are above the critical threshold for severe flooding, they are closer to historical Category 3 events, warranting increased attention. NOAA's Flood Likelihood Analysis maintains a low likelihood percent, supporting the assessment of an elevated but not severe flood risk.
CATEGORY 4
WHAT Likely coastal flooding during high tide periods, with potential for significant water levels rising near shorelines and impacting property.
WHEN From around 5:00 AM to 6:00 AM PST and from approximately 2:00 PM to 3:00 PM PST.
IMPACTS Likely flooding in coastal zones, with potential property damage in low-lying areas. Preparations should be made for road closures and water reaching structures near the coast.
On Day 3, barometric pressure readings are notably lower at approximately 1029 hPa during both high tides, which is closer to the threshold observed in historical Category 4 events. This decrease in pressure, coupled with NOAA's slight increase in flood likelihood percent to 1%, indicates a higher risk of flooding compared to the previous days. The conditions are more aligned with those experienced during past Category 4 events, suggesting a higher potential for property-affecting floodwaters.
Residents and businesses near Redondo Beach 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. It is advisable to 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.
