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 02:00 AM to 03:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure during the high tide at 02:36 AM is 1015.8 hPa, which is significantly higher than the threshold associated with past flooding events. The tide height is not provided, but the NOAA flood likelihood for this day is low, with a 0.0% chance of flooding and a distance to threshold of -1.33m, indicating that the tide is not expected to reach levels that have historically caused flooding. Wind direction data is not available for this specific forecast but considering the historical data, unless there are strong winds from the W/NW, the risk remains low.
CATEGORY 2
WHAT Slight risk of coastal flooding near shorelines and low-lying areas.
WHEN From 03:00 AM to 04:00 AM PST.
IMPACTS Potential for minor overflow onto coastal roads and footpaths.
The barometric pressure at the time of high tide at 03:12 AM is 1019.3 hPa, which is well above the threshold that indicates a risk of flooding. The NOAA flood likelihood remains low with no expected flooding and a distance to threshold of -1.22m. The weather conditions appear stable and do not suggest significant flood risk.
CATEGORY 4
WHAT Elevated risk of coastal flooding with potential property damage.
WHEN From 03:30 AM to 04:30 AM PST and again from 05:30 PM to 06:30 PM PST.
IMPACTS Likely flooding of properties in low-lying coastal areas, with road closures and disruptions to local infrastructure possible.
On this day, the barometric pressure during high tides at both 03:42 AM and 06:00 PM is notably lower (1003.2 hPa and 1002.1 hPa respectively), approaching the threshold associated with previous Category 4 events. Although NOAA's flood likelihood data indicates a low chance of flooding with a distance to threshold of -1.39m, the significantly lower barometric pressure combined with high tides could result in more severe conditions than predicted by NOAA's model. Historical events suggest that such pressure levels can lead to substantial flooding, especially if accompanied by strong winds from the W/NW direction.
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 and adhere to any evacuation orders or safety instructions provided by emergency services.
