Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 11:00 AM to 1:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be 1007.780029296875 hPa during the high tide at 11:48 AM, which is higher than the threshold that typically indicates a higher risk of flooding (992.8 hPa). However, given the historical data, a Category 3 event had a pressure of 1006.1 hPa with a higher tide height of 17.460 Ft compared to today's expected high tide. Wind direction is not provided but should be monitored if from W/NW as it can push water ashore. NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this date.
CATEGORY 4
WHAT Coastal flooding likely but not expected to cause major property damage.
WHEN Highest risk periods are around the high tides at 7:18 AM and 1:42 PM PST.
IMPACTS Flooding of coastal areas, roads, and possibly properties close to the shoreline. Precautionary measures recommended for waterfront businesses and residences.
The barometric pressure is lower on this day, with readings of 1001.52001953125 hPa and 1001.1500244140625 hPa during high tides, which is closer to the threshold that increases flood risk. The tide heights are not provided but should be closely watched as they approach the levels seen in historical Category 3 events. NOAA's Flood Likelihood Analysis still indicates a low likelihood of flooding for this date.
CATEGORY 5
WHAT Coastal flooding likely and may cause property damage.
WHEN Highest risk period around the high tide at 8:48 AM PST.
IMPACTS Significant flooding expected in coastal areas, with potential damage to properties and infrastructure. Road closures and disruptions to local services are possible.
On this day, the barometric pressure during high tide drops to 996.6500244140625 hPa, which is below the critical threshold and paired with a high tide could indicate a significant risk for flooding similar to or exceeding Category 4 events from historical data. The wind direction will be a critical factor to monitor, especially if from W/NW. NOAA's Flood Likelihood Analysis maintains a low likelihood rating for this date; however, given the pressure data, vigilance is advised.
Residents and businesses near the shore 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 heed any evacuation orders or safety instructions provided by emergency services.
