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 6:54 PM to 8:42 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 1001.9 hPa and 1000.3 hPa, the likelihood of a severe flood is reduced despite the high tide levels. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding with a 0.0% chance, which supports the assessment that while there may be minor coastal flooding due to high tides, significant flooding is unlikely.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground level in some areas.
WHEN From 7:48 AM to 9:12 PM PST.
IMPACTS Increased risk of flooding in low-lying areas and roads near the shoreline. Some roadways may become impassable due to rising water levels.
On this day, the barometric pressure during high tide in the morning is closer to historical flood event thresholds at 997.98 hPa, which warrants closer monitoring. However, the evening high tide shows a pressure of 1003.61 hPa, suggesting less risk during that period. NOAA's analysis still indicates a low likelihood of flooding, which aligns with the pressure data to suggest that while there is an elevated risk compared to Day 1, widespread or severe flooding is not anticipated.
CATEGORY 2
WHAT Minor coastal flooding possible with water levels slightly above normal high tide marks.
WHEN From 8:54 AM to 9:42 PM PST.
IMPACTS Some overflow onto coastal roads and walkways near the beach. Low-lying properties may experience minor inundation.
The barometric pressure for both high tides on Day 3 is at 1002.1 hPa, which does not indicate a significant risk of severe weather or flooding. The NOAA Flood Likelihood Analysis continues to show a low likelihood of flooding with no expected deviation from normal conditions beyond minor effects due to high tides.
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.
