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 5:00 PM to 9:00 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 1009.280029296875 hPa and 1005.97998046875 hPa during high tides, the likelihood of severe flooding is reduced despite the tide levels being above 16 feet. The NOAA flood likelihood is also reported as low for this day, which aligns with the pressure data suggesting a lower risk of flooding.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for up to 1 foot of inundation in susceptible areas near shorelines and low-lying regions.
WHEN From 10:00 AM to 2:00 PM PST and again from 8:00 PM to midnight PST.
IMPACTS Moderate flooding of coastal areas, with some roads potentially becoming impassable. Property damage is unlikely but possible in very low-lying areas.
On this day, the barometric pressure readings are closer to the historical events that have resulted in flooding, with pressures of 1005.8900146484375 hPa and 1004.9299926757812 hPa during high tides. The tide levels are also expected to be high, which increases the risk of flooding. However, the NOAA flood likelihood remains low, which suggests that while there is an elevated risk compared to Day 1, severe flooding is still not anticipated.
CATEGORY 4
WHAT Likely coastal flooding with potential for significant property damage in low-lying areas.
WHEN From 7:00 AM to 11:00 AM PST and again from approximately 8:00 PM to midnight PST.
IMPACTS Likely flooding of coastal and low-lying areas with a possibility of property damage due to water inundation. Residents should be prepared for road closures and take action to protect property.
The barometric pressure on this day drops significantly to around 999.4199829101562 hPa during both high tides, which is much closer to the threshold associated with historical flood events. Combined with high tide levels, there is an increased risk of significant flooding similar to past Category 4 events. The NOAA flood likelihood data is not indicating a high probability of flooding; however, given the historical data and the significant drop in pressure, there is a heightened concern for potential flooding impacts.
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 adhere to any evacuation orders or safety instructions provided by emergency services.
