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 5:00 PM to 7:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be around 1013.3 hPa during the high tide at 6:00 PM, which is higher than the threshold that has historically led to significant flooding events. The tide height is expected to be lower than the historical events that caused major flooding. However, given the high tide at 18:00 and the proximity to the lower barometric pressure threshold, there is a risk for minor coastal flooding.
CATEGORY 5
WHAT Likely coastal flooding with potential property damage. Inundation may exceed 1 foot above ground level in shorelines and low-lying areas.
WHEN From early morning around 5:00 AM continuing to late evening around 7:00 PM PST.
IMPACTS Moderate flooding of coastal areas, with potential for property damage. Road closures likely, and residents in flood-prone areas should be prepared for evacuation if necessary.
The barometric pressure is forecasted to drop significantly below the critical threshold of 992.8 hPa, reaching as low as 989.75 hPa during the high tide at 6:42 PM. This is coupled with a high tide event, which greatly increases the likelihood of significant flooding. The conditions are similar to historical Category 5 events, indicating a strong potential for property damage due to flooding.
CATEGORY 6
WHAT Severe coastal flooding expected with extensive property damage likely. Inundation levels may be dangerous and could pose a threat to life and property.
WHEN From early morning around 6:00 AM continuing to late evening around 8:00 PM PST.
IMPACTS Extensive flooding of coastal and low-lying areas, significant property damage expected. Major road closures and evacuations likely. Residents should follow local authority guidance and be prepared for emergency situations.
The barometric pressure remains well below the critical threshold at approximately 990.56 hPa during both high tides at 6:00 AM and 7:30 PM. The persistent low pressure combined with high tides suggests a scenario similar or even more severe than historical Category 5 events, leading to a Category 6 prediction for this day. The risk of severe flooding is exacerbated by these conditions.
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. Follow all advice from local authorities regarding evacuation orders and flood preparation measures. Ensure that emergency kits are ready and that plans are in place for quick action if needed.
