Redondo Beach, WA
CATEGORY 3
WHAT
Minor but notable coastal flooding conditions are possible during the early morning and late afternoon high tides. Expected peak water levels near 20.5 ft, with relatively moderate atmospheric pressure around 1018–1015 hPa.
WHEN
From around 06:00 PST through 07:00 PST and again near 16:30 PST.
IMPACTS
• Minor inundation of low-lying areas adjacent to the shoreline and waterfront parks.
• Potential for brief ponding on some roads very close to shore.
• NOAA’s forecast indicates about a 5.3% flood likelihood despite labeling it “High,” which is lower than the 8–11% likelihood seen in previous Category 3 events.
• Tides will be near 20.5 ft, comparable to some past Category 3 events, but the barometric pressure is higher, suggesting less severe risk.
• Winds are from the south at modest speeds, reducing any additional push of seawater onto the coast.
CATEGORY 2
WHAT
No significant flooding is expected. While tides may again approach around 20.5 ft, the barometric pressure remains relatively high (1016–1023 hPa), and NOAA’s flood likelihood for this day is lower (3.8%).
WHEN
Near 06:30 PST and 17:24 PST, coinciding with high tides.
IMPACTS
• Little to no flooding impacts are anticipated.
• Only routine caution near the shoreline is advised.
• Historically, Category 2 events rarely lead to flooding unless barometric pressure is significantly lower or wind directions are more onshore.
• Current forecasts show stable weather conditions with calm to moderate winds, further lowering the flood risk.
CATEGORY 3
WHAT
Near-flood conditions around high tide, especially in early morning and early evening. Tides may reach approximately 20.5 ft, with barometric pressure near 1021–1022 hPa, and NOAA’s indicated flood likelihood of 5.0%.
WHEN
Highest risk from around 06:54 PST to 07:30 PST and again near 18:18 PST.
IMPACTS
• Possible minor flooding in low-lying coastal spots, with only brief nuisance impacts expected.
• Roads close to the shoreline might experience minor ponding but are unlikely to be significantly affected.
• Conditions resemble other low-intensity flood events, with tides exceeding 20 ft but under higher atmospheric pressure.
• Compared to historical higher-category floods, barometric pressure remains well above the 992–1002 hPa range typically associated with more severe flooding.
• Wind direction remains mostly south/southeast, which usually does not worsen surge conditions along this coastline.
You 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.
• Categories 1-2: No risk of flooding.
• Category 3: Close to a flood event and worth monitoring.
• Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
