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 8:00 PM to 10:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be around 998.9 hPa to 999 hPa during the high tides, which is higher than the threshold that historically indicates severe flooding (992.8 hPa). However, the tide levels are expected to be high at around 16.404 ft in the morning and 20.191 ft in the evening, which warrants attention. The NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this date, with a distance to threshold of -0.99m from the flood threshold of 2.1m. Considering these factors and comparing them with historical events, particularly the Category 3 event on 12/27/2023 with a tide height of 17.460 Ft and a barometric pressure of 1006.1 hPa, there is a potential for minor coastal flooding but not at a level that would cause major property damage.
CATEGORY 2
WHAT Coastal conditions expected to be mostly stable with a very low chance of flooding.
WHEN All day.
IMPACTS No significant impacts expected; normal tidal conditions likely.
On this day, the barometric pressure will be slightly lower than on Day 1, ranging from approximately 994.1 hPa to 996.7 hPa during high tides. The tide levels are forecasted to be lower than on Day 1, with no tide levels reaching or exceeding the critical height of 21 ft that has been associated with past flooding events. NOAA's Flood Likelihood Analysis also suggests a low likelihood of flooding for this date, with a distance to threshold of -1.1m from the flood threshold of 2.1m. Given these observations and the absence of any critical indicators for severe flooding, the risk category is assessed as Category 2.
CATEGORY 2
WHAT Low risk of coastal flooding with no significant tidal disruptions anticipated.
WHEN All day.
IMPACTS Expected normal tidal activity with no immediate threat to property or infrastructure.
The barometric pressure remains relatively stable and above the critical threshold for severe weather conditions that could lead to flooding, with readings around 996.7 hPa during high tides. The tide levels are not expected to reach heights that have historically resulted in flooding in Redondo Beach, WA. NOAA's Flood Likelihood Analysis continues to show a low likelihood of flooding for this date, with a distance to threshold of -1.16m from the flood threshold of 2.1m. Based on these factors and historical comparisons, the flood risk remains categorized as Category 2.
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 conditions change unexpectedly. Always follow instructions from local authorities and emergency services regarding evacuations or safety measures related to potential coastal flooding events.
