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 4:00 PM to 6:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure at the time of high tide is forecasted to be 995.5 hPa, which is higher than the threshold that indicates a significant risk of flooding (992.8 hPa). However, it is still relatively low and, when paired with a high tide level of approximately 18.05 feet (converted from meters), suggests a potential for minor coastal flooding. The wind direction is from the northwest, which may contribute to water being pushed toward the shore but is not as critical as the pressure and tide height in this scenario. Comparing with historical events, particularly the Category 3 event on 12/27/2023 with a tide height of 17.460 Ft and a barometric pressure of 1006.1 hPa, today's conditions are somewhat similar but with a lower barometric pressure which increases the risk slightly.
CATEGORY 2
WHAT Coastal conditions expected to be mostly stable with a very low risk of flooding.
WHEN The entire day, with special attention during high tide at approximately 5:42 PM PST.
IMPACTS No significant impacts expected. Normal tidal fluctuations may cause minor pooling in very low-lying areas.
On this day, the barometric pressure during high tide will be around 998.75 hPa, which is well above the critical threshold for significant flooding risk. The tide level is also lower than on Day 1, with a high tide prediction of approximately 17.7 feet (converted from meters). Wind conditions are not provided but given the higher pressure and lower tide levels compared to historical events that caused more severe flooding, the risk on this day is categorized as very low.
CATEGORY 2
WHAT No significant coastal flooding expected.
WHEN Throughout the day, monitoring high tide at approximately 6:12 PM PST.
IMPACTS No anticipated impacts beyond typical tidal effects.
The barometric pressure for the high tide event on this day is forecasted to be around 997.24 hPa, which does not indicate a significant risk for flooding when compared to historical data. The high tide level is expected to be around 18.72 feet (converted from meters), which is lower than the Category 4 and Category 5 events in our historical data set. Without additional data on wind conditions or NOAA's flood likelihood for this specific day, we maintain a low-risk forecast based on available information.
Residents and visitors 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 advisories or evacuation orders that may be issued.
