Redondo Beach, WA
Below is a three-day coastal flood potential forecast for Redondo Beach, WA, based on the provided tide heights, barometric pressures, and historical reference events. No NOAA flood likelihood data were available.
CATEGORY 3
WHAT
Minor to moderate coastal flooding is possible around the time of the late afternoon to early evening high tide (approximately 19.2 ft), making conditions close to a flood event but not expected to cause significant property damage.
WHEN
• Highest concern near the peak high tide at around 7:18 PM on 2025-05-14.
IMPACTS
• Minor flooding could briefly affect low-lying areas, roadside shoulders, and parts of coastal walkways.
• Beach erosion is possible but should be limited given relatively moderate wind speeds and pressure.
• The tide height of around 19.2 ft is below the ~20+ ft levels often associated with higher-category past events.
• Barometric pressure is around 1005 hPa, which is not low enough to substantially increase flood risk.
• Historical comparisons (e.g., 12/27/2023 Category 3 event at 17.46 ft tide, 1006.1 hPa) support this moderate categorization.
CATEGORY 3
WHAT
Minor coastal flooding possible again as the tide approaches around 19.2 ft. Conditions should be monitored, though widespread damage is not anticipated.
WHEN
• Highest tide at about 7:54 PM on 2025-05-15.
IMPACTS
• Minor tidal overflow could impact low-lying coastal roadways and flood-prone spots.
• Beach access points and park areas near the waterline may experience brief inundation.
• Barometric pressure is higher (around 1012 hPa), which reduces the likelihood of a severe flood scenario.
• Historically, tides under ~20.5 ft with moderately higher pressure typically correspond to mid-range (Category 3) events.
CATEGORY 3
WHAT
Coastal waters may again reach near 19 ft during the evening high tide. Although this is substantially elevated, the moderate barometric pressure indicates only minor flooding concerns.
WHEN
• Greatest risk near peak tide time around 8:42 PM on 2025-05-16.
IMPACTS
• Minor tidal flooding may affect beach areas, low-lying roads, and harbors.
• No major property damage is expected.
• Barometric pressure near 1008 hPa is higher than the thresholds typically associated with major coastal flooding.
• Comparisons to historical Category 3 events, which often feature tides in the 17–20 ft range accompanied by moderate pressure, suggest a similar outcome.
