Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.2 feet above ground level near shorelines and low-lying areas due to high tide and moderate barometric pressure.
*WHEN From 07:00 AM to 09:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure during the high tide at 08:18 is 1030.56 hPa, which is significantly higher than the threshold associated with previous flooding events. The NOAA Flood Likelihood Analysis indicates a high likelihood of flooding at 26.3%, but the high pressure suggests that the severity may not be as high as past Category 4 or 5 events. The tide height is not provided, but the distance to threshold is -0.2m, indicating that water levels are close to flood thresholds. Wind direction is not specified, but if from W/NW, it could contribute to water level rise.
CATEGORY 4
WHAT Coastal flooding likely with potential for property damage due to lower barometric pressure and high tide.
WHEN From 07:30 AM to 09:30 AM PST and from 7:30 PM to 9:30 PM PST.
IMPACTS Likely flooding of properties especially those close to the shoreline, with possible road closures and disruptions to daily activities.
The barometric pressure at high tide (08:48) is forecasted at 1018.05 hPa, which is closer to the threshold of past Category 4 events but still above the critical threshold of <=1002 hPa. The NOAA Flood Likelihood Analysis maintains a high likelihood of flooding at 25.2%. Given the lower pressure compared to Day 1 and proximity to historical Category 4 conditions, there is an increased risk of flooding that may cause property damage.
CATEGORY 2
WHAT Low risk of flooding due to relatively high barometric pressure despite high tide levels.
WHEN Potential for higher water levels around the time of high tide in the late evening.
IMPACTS No significant impacts expected; however, monitoring is advised for any changes in conditions.
On Day 3, the barometric pressure during the high tide at 22:12 is forecasted at 1027.66 hPa, which is much higher than the critical threshold for severe flooding events. The NOAA Flood Likelihood Analysis indicates a much lower likelihood of flooding at 12.4% compared to previous days. While the tide levels may be elevated, the high barometric pressure suggests a lower risk of significant flooding impacts.
You 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. Always consult local authorities or experts for final decision-making in flood-related situations.
