Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
*WHEN From 6:00 PM to 9:00 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 associated with past flooding events, suggesting less severe weather conditions. However, the high tide at 5:30 AM with a mean pressure MSL of 1012.5 hPa is close to the threshold that increases the likelihood of flooding. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the current weather data showing overcast conditions but no significant precipitation. The wind direction is from the SSE, which is not directly from the W/NW as in the historical event on 12/17/2022 that could push more seawater towards the coast. Therefore, while there is a minor risk due to high tide, the overall risk remains moderate.
CATEGORY 2
WHAT Coastal conditions are being monitored for potential flooding, but current data suggests a low likelihood of significant impact.
WHEN Monitoring throughout the day, especially during high tide times.
IMPACTS Potential for minor pooling in very low-lying areas but no significant flooding expected.
The barometric pressure readings for both high tides are above the critical threshold, indicating stable weather conditions unlikely to contribute to severe flooding. The NOAA Flood Likelihood Analysis continues to show a low likelihood of flooding for this date. Wind direction and other weather conditions are not indicating a significant risk for flooding at this time.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to lower barometric pressure and high tide levels.
WHEN Increased vigilance during high tides, particularly around 10:00 PM PST when pressure is lowest.
IMPACTS Possible minor coastal flooding in susceptible areas. Be prepared for water on roads and in basements of vulnerable structures.
The barometric pressure during both high tides is lower than on previous days, nearing the threshold that historically increases flood risks. The NOAA Flood Likelihood Analysis still indicates a low likelihood of flooding; however, given the lower pressures and consistent high tide levels, there is an elevated risk compared to Day 2. The wind direction will need to be monitored as it can influence water levels and exacerbate flooding if coming from W/NW.
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 heed any evacuation orders or safety instructions.
