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 5:00 AM PST and 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 readings for the high tides on this day are significantly higher than the threshold that has historically indicated severe flooding events. The tide heights, while elevated, are not reaching the levels that have been associated with major flood events in the past. The NOAA flood likelihood is low, with a 0.0% chance of flooding, which supports the assessment that while there is a minor risk due to high tides, significant flooding is unlikely.
CATEGORY 2
WHAT Minor coastal flooding potential due to high tides. Inundation is possible but expected to be minimal.
WHEN Highest risk near the time of high tide at approximately 4:00 AM PST and again at around 5:30 PM PST.
IMPACTS Low-lying areas and roads near the shoreline may experience minor flooding. Water levels may approach but not exceed known thresholds for property damage.
Similar to Day 1, the barometric pressure is well above the critical threshold associated with significant flooding events. The tide levels are also below those seen in historical Category 3 or higher events. NOAA's flood likelihood remains low at 0.0%, indicating a continued low risk of significant flooding despite the presence of high tides.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to high tides and lower barometric pressure. Some property damage is possible if preventative measures are not taken.
WHEN Highest risk during high tide periods around midday (1:00 PM PST) and early evening (6:00 PM PST).
IMPACTS Potential for moderate flooding of properties, especially those that are not adequately protected or are typically vulnerable to high tide events. Roads and infrastructure close to the shoreline may be at risk.
On this day, the barometric pressure drops closer to the threshold that has historically indicated more severe flooding events (below 992.8 hPa). While it does not reach this critical point, it is significantly lower than on the previous days, which warrants a higher category rating. The tide height is also approaching levels seen in past Category 4 events but does not exceed them. NOAA's flood likelihood data is not indicating an increased risk; however, given the lower barometric pressure and higher tides, there is an elevated concern compared to the previous days.
Residents and businesses near the shore 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 follow any evacuation orders or safety instructions as issued by emergency services.
