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 5:00 AM to 8:00 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 has historically led to severe flooding, suggesting less severe weather conditions for this event. The high tide at 06:24 with a mean pressure MSL of 1017 hPa is not indicative of extreme flooding risk, especially when compared to historical events with much lower pressures. NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding at 3.9%, which supports the assessment of a Category 3 event.
CATEGORY 4
WHAT Coastal flooding likely, with potential for property damage in vulnerable areas.
WHEN From 5:30 AM to 8:30 AM PST and from 5:00 PM to 8:00 PM PST.
IMPACTS Flooding of properties in low-lying areas, road closures, and disruptions to daily activities.
The barometric pressure is lower on this day, with a mean pressure MSL of 1002.36 hPa during the morning high tide and 1005.62 hPa during the evening high tide. This is closer to the historical Category 4 events, suggesting an increased risk of flooding. NOAA's Flood Likelihood Analysis indicates a high likelihood of flooding at 10.1%, which is significant and warrants a Category 4 classification.
CATEGORY 3
WHAT Minor coastal flooding expected similar to Day 1 conditions.
WHEN From 6:00 AM to 9:00 AM PST and from 6:00 PM to 9:00 PM PST.
IMPACTS Minor but noticeable flooding in low-lying coastal areas and potential for isolated disruptions.
The barometric pressure remains high at around 1017.25 hPa during both high tides, which does not suggest severe weather conditions that could lead to major flooding. The NOAA Flood Likelihood Analysis also indicates a high likelihood of flooding at 7.9%, but given the higher barometric pressure and the distance to the flood threshold, it is assessed as a Category 3 event.
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.
