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 1:00 PM to 3:00 PM 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 indicates severe weather conditions and potential flooding. The high tide at 14:30 with a mean pressure MSL of 1006.3 hPa does not approach the critical lower pressure levels seen in historical Category 5 events. Additionally, the NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, with a distance to threshold of -1.31m, which is considerably below the flood threshold level.
CATEGORY 2
WHAT Coastal conditions expected to be similar to Day 1 with minor coastal flooding possible.
WHEN From 2:00 PM to 4:00 PM PST.
IMPACTS Similar minor impacts as Day 1 with potential for low-lying area inundation and isolated road closures.
Continuing the trend from Day 1, the barometric pressure remains high at a mean pressure MSL of 1006.8 hPa during the early high tide and 1005.4 hPa during the later high tide, indicating stable weather conditions less conducive to severe flooding. The NOAA Flood Likelihood Analysis maintains a low likelihood prediction for this date as well.
CATEGORY 3
WHAT Increased risk of coastal flooding due to lower barometric pressure and continued high tides.
WHEN From 3:00 PM to 5:00 PM PST.
IMPACTS Increased potential for minor property damage and more widespread inundation of low-lying areas. Residents should be prepared for possible road closures and disruptions.
On Day 3, the barometric pressure drops closer to levels that have historically been associated with more significant flooding events (1003.5 hPa during early high tide and further dropping to 1000.4 hPa by late afternoon). While still not as low as the most severe events on record, this decrease in pressure warrants a higher flood category rating, especially when considering the wind direction from W/NW which can push water towards the shore. The NOAA Flood Likelihood Analysis continues to indicate a low likelihood of flooding; however, given the lower barometric pressure readings and historical precedent, there is an increased risk compared to the previous days.
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.
