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, coinciding with the high tide.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure during the high tide is significantly higher than the threshold that has historically led to severe flooding events. With a mean pressure MSL of 1022.469970703125 hPa during the first high tide and 1025.4000244140625 hPa during the second, the risk of a severe flood event is low. The NOAA's Flood Likelihood Analysis indicates a very low likelihood of flooding at 0.2%, with a distance to threshold of -1.02m, which supports the assessment of a Category 2 flood potential for this day.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for up to 1 foot of inundation above ground level in some shorelines and low-lying areas.
WHEN Highest risk near the times of high tide, particularly around 5:54 AM PST.
IMPACTS Increased flooding of low-lying coastal areas and roads, with some road closures likely. Minor property damage may occur in vulnerable locations.
The barometric pressure is lower on this day, with a mean pressure MSL of 1020.9500122070312 hPa during the morning high tide and 1019.3300170898438 hPa in the afternoon, indicating a slightly increased risk compared to Day 1. The NOAA's Flood Likelihood Analysis still categorizes the flood likelihood as low at 1.7%, but with a smaller distance to threshold (-0.68m) than on Day 1. The wind direction is not provided but considering the other factors, there is an elevated risk warranting a Category 3 classification.
CATEGORY 4
WHAT Likely coastal flooding with potential for significant property damage in some areas.
WHEN High risk during high tide periods, especially around 6:24 AM PST.
IMPACTS Flooding of coastal properties and infrastructure likely, with moderate property damage possible. Road closures and disruptions to daily activities expected in affected areas.
On Day 3, the barometric pressure drops further to a mean pressure MSL of 1018.6599731445312 hPa during the morning high tide, which is closer to historical events that resulted in more significant flooding (Category 4). The NOAA's Flood Likelihood Analysis shows an increased likelihood percent at 3.9%, with a distance to threshold of -0.52m, indicating a higher risk than the previous days. Given these factors and comparing them to historical data, Day 3 presents conditions that are more conducive to flooding, leading to a Category 4 classification.
Residents and businesses 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.
