Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
WHEN From late evening to early morning PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold associated with past flooding events, suggesting less severe weather conditions. However, the high tide at 19:30 with a mean pressure MSL of 1007.3 hPa, although not critically low, still warrants attention due to its proximity to historical Category 3 events. Wind direction is not provided but should be monitored if from the W/NW as it could push water ashore.
CATEGORY 3
WHAT Continued risk of minor coastal flooding, especially during high tide periods.
WHEN Peak risk near the high tide at 20:18 PST.
IMPACTS Similar impacts as Day 1 with potential for minor flooding in susceptible areas.
The mean pressure MSL at the time of high tide is lower than on Day 1, at 1005.5 hPa, which is closer to historical Category 3 events but still above critical thresholds. The NOAA flood likelihood remains low, which reduces the overall risk despite the lower pressure.
CATEGORY 2
WHAT Decreased risk of coastal flooding with improving conditions.
WHEN Lowest risk throughout the day due to higher barometric pressure.
IMPACTS Minimal impacts expected; normal tidal conditions may resume without significant flooding.
The barometric pressure has increased slightly compared to Day 2, indicating improving weather conditions and a reduced likelihood of flooding. The high tide levels are not expected to reach thresholds that would result in significant flooding based on historical data comparison and NOAA's low flood likelihood prediction.
Residents and visitors 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 advisories or evacuation orders that may be issued.
