Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected due to high tides, but current barometric pressure suggests less severe weather conditions. Possible inundation of low-lying areas near shorelines.
WHEN The highest risk is around the high tide times of 02:24 and 12:24 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 led to severe flooding events. While the tide heights are not trivial, they do not reach the levels seen in past Category 4 or higher events. NOAA's Flood Likelihood Analysis indicates a "Low" likelihood of flooding with a 0.0% chance, which supports the assessment that while there may be minor coastal flooding, it is unlikely to cause significant damage or pose a severe risk.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to a combination of high tide and lower barometric pressure. Potential for water inundation in more susceptible areas.
WHEN The highest risk coincides with the high tide at 18:12 PST.
IMPACTS Increased likelihood of minor to moderate flooding in low-lying areas and roads near the shoreline. Some property damage is possible if preventative measures are not taken.
The barometric pressure at the time of high tide is closer to historical events that have resulted in Category 4 flood events. However, the NOAA Flood Likelihood Analysis still indicates a "Low" likelihood with a 0.0% chance, suggesting that while the risk is elevated compared to Day 1, it may not reach the severity needed for major concern. The wind direction and speed are not provided but would be a contributing factor if from W/NW.
CATEGORY 5
WHAT High likelihood of significant coastal flooding due to very low barometric pressure and high tide levels. Expect property damage and consider evacuation from the most vulnerable areas.
WHEN The highest risk is around the high tide time of 18:54 PST.
IMPACTS Likely flooding with potential for significant property damage, especially in low-lying areas and regions without adequate flood defenses. Road closures and disruptions to local infrastructure are possible.
The barometric pressure is forecasted to be below the critical threshold of 992.8 hPa during high tide, which historically has led to severe flooding events (Category 5). This day's conditions are similar to those seen during the historical Category 5 event on 12/27/2022, with both very low barometric pressure and high tide levels. NOAA's Flood Likelihood Analysis does not indicate an increased likelihood percentage; however, given the significant deviation in barometric pressure from normal levels, this forecast leans towards a more cautious approach.
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 consider evacuation plans if you reside in vulnerable coastal areas, especially on Day 3 when significant flooding is likely.
