Redondo Beach, WA
CATEGORY 4
WHAT Moderate coastal flooding expected. Possible inundation of up to 1-2 feet above ground level near shorelines and low-lying areas.
*WHEN From 5:00 AM to 7:30 AM PST, and again from 6:00 PM to 8:30 PM PST.
IMPACTS Moderate flooding of low-lying areas, parks, and roads. Isolated road closures possible, with some properties at risk of inundation.
The barometric pressure readings for the high tides on this day are significantly below the threshold of 992.8 hPa, which greatly increases the likelihood of flooding. The tide heights are not provided, but given the pressure readings and historical data, there is a moderate risk of flooding. The wind direction is not specified; however, if winds are from the W/NW as they often are during flood events in this region, this could exacerbate the situation. Comparing with the historical event on 12/17/2022, which was a Category 5 event with a much lower pressure reading and higher tide height, today's risk is assessed as Category 4 due to the very low pressure but without confirmation of equally extreme tide levels.
CATEGORY 2
WHAT Low risk of coastal flooding. No significant inundation expected near shorelines and low-lying areas.
WHEN The entire day presents a low risk due to favorable conditions.
IMPACTS Minimal impact expected. Normal tidal conditions with no significant overflow.
The barometric pressure has risen significantly compared to the previous day, indicating improved weather conditions and a reduced likelihood of severe weather that could lead to flooding. The NOAA flood likelihood is low for this date, and the tide data does not suggest extreme high tides that would contribute to flooding risks. This day's forecast aligns more closely with historical Category 1 events where no flooding occurred.
CATEGORY 1
WHAT No risk of coastal flooding. Normal tidal activity expected without any significant overflow.
WHEN The entire day presents no risk due to stable conditions.
IMPACTS No impacts from flooding are anticipated. Daily activities should not be affected by tidal conditions.
Both the barometric pressure and NOAA's flood likelihood analysis indicate a very low risk of flooding for this date. The pressure is well above the threshold that typically indicates severe weather conditions that could lead to flooding. Additionally, there is no indication from NOAA that high tide levels will approach or exceed flood thresholds. This forecast is consistent with historical Category 1 events where no flooding was observed.
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.
