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 6:00 PM to 8:00 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 19:48 with a mean pressure MSL of 1006.8200073242188 hPa indicates a potential for minor coastal flooding, especially in conjunction with the wind direction from the north, which could push water towards the shore. The NOAA Flood Likelihood Analysis reports a low likelihood of flooding for this date, which aligns with the predicted Category 2 event.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for up to 1 foot of inundation in low-lying areas near the shoreline.
WHEN From 5:00 AM to 7:00 AM PST and again from 6:00 PM to 8:00 PM PST.
IMPACTS Moderate flooding of coastal areas, parks, and roads with possible property damage in vulnerable locations.
The barometric pressure is lower than on Day 1, nearing the threshold that has historically indicated more significant flood events. The high tide at 20:12 with a mean pressure MSL of 1003.530029296875 hPa and again at 06:00 with a mean pressure MSL of 1000.6199951171875 hPa suggests an increased risk compared to Day 1. The NOAA Flood Likelihood Analysis still reports a low likelihood of flooding, but given the lower barometric pressures and high tides expected, there is an elevated risk warranting a Category 3 prediction.
CATEGORY 4
WHAT Likely coastal flooding with significant inundation expected in low-lying areas near shorelines.
WHEN From 5:30 AM to 7:30 AM PST and again from approximately 6:30 PM to 8:30 PM PST.
IMPACTS Likely flooding of coastal areas, parks, roads, and potential property damage in vulnerable locations. Residents should be prepared for possible evacuations.
The barometric pressure on Day 3 is forecasted to be at or below the critical threshold of 992.8 hPa during high tides at both 20:42 and 06:54, which historically correlates with significant flood events. This situation is very similar to the Category 4 event on January 7th, 2022. The NOAA Flood Likelihood Analysis maintains a low likelihood percentage; however, given the historical data and current barometric pressure readings paired with high tide levels, there is a strong indication of likely flooding that could cause property damage.
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 follow any evacuation orders or safety instructions as issued by emergency services.
