Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 4:00 AM to 6:00 AM PST and from 4:00 PM to 6:00 PM 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 indicated severe flooding events. With pressures of 1020.4 hPa and 1022.5 hPa during the high tides, the risk of flooding is lower despite the high tide levels. The NOAA flood likelihood for this day is also low, with a 0.0% likelihood reported, which supports the lower category prediction.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN From 5:00 PM to 7:00 PM PST.
IMPACTS Increased flooding of low-lying coastal areas and roads, with possible property damage in vulnerable locations.
On this day, the barometric pressure during high tides drops to around 1014 hPa, which is closer to historical events that have resulted in flooding. However, it is still above the critical threshold observed in past Category 4 or higher events. The NOAA flood likelihood remains low, which suggests that while there is an increased risk compared to Day 1, widespread or severe flooding is not anticipated.
CATEGORY 5
WHAT Significant coastal flooding expected with potential for substantial property damage.
WHEN From 5:00 AM to 7:00 AM PST and again from 5:00 PM to 7:00 PM PST.
IMPACTS Major flooding of coastal areas, roads, and properties with a significant risk of damage. Evacuations may be necessary in some areas.
The barometric pressure on this day is forecasted to be at a critical low of around 1001.7 hPa during both high tides, which is similar to the pressure observed during historical Category 5 events. This greatly increases the risk of severe flooding, especially when combined with high tide levels. The NOAA flood likelihood data is not provided for this day, but given the significant drop in pressure and historical comparisons, a higher category rating is warranted.
Residents and businesses near the shore should prepare for potential flooding impacts. Monitor updates from local authorities and be ready to follow evacuation orders if issued. Ensure that emergency kits are prepared and consider moving vehicles and valuables to higher ground if located in flood-prone areas. Stay informed on the latest weather forecasts and tide predictions as conditions can change rapidly.
