Redondo Beach, WA
CATEGORY 2
WHAT
No significant coastal flooding is expected on Day 1. Although tide levels will reach around 18 ft, the barometric pressure remains relatively high (above 1000 hPa), and NOAA’s flood likelihood is at 0%.
WHEN
Highest tides near late morning (around 11:42) and again around 17:00.
IMPACTS
No notable flooding impacts anticipated. Routine coastal conditions.
Tide heights are elevated compared to some minor historical events, but the barometric pressure is well above the low thresholds typically associated with flood events (well above 992.8 hPa). NOAA’s latest data indicates a 0% flood likelihood. These factors collectively support a Category 2 rating, meaning no risk of flooding.
CATEGORY 2
WHAT
No significant flood risk is expected on Day 2. Tides will again approach 18 ft in the early morning hours, with daytime high tides below 20 ft. Barometric pressure remains moderate (around 1005–1006 hPa).
WHEN
Highest tides near 02:48 and early afternoon around 13:00.
IMPACTS
No anticipated flooding. Normal marine conditions along the shoreline.
Although the tide height is comparable to Day 1, it remains well below 21 ft, and the barometric pressure is comfortably above the critical low threshold. NOAA’s flood likelihood remains at 0%. Conditions remain more stable than those seen in historical Category 3 or higher events.
CATEGORY 3
WHAT
Conditions move closer to a potential flood event on Day 3. Tide heights will near 19 ft in the early morning (around 03:12) and again into the evening (18:48), coinciding with lower barometric pressures (dropping below 1000 hPa).
WHEN
Highest overall tides late overnight (03:12) and early evening (18:48), when pressures are forecast around 998–996 hPa.
IMPACTS
While widespread flooding is not expected, minor concerns could arise in very low-lying areas if localized weather factors (wind shifts or brief drops in pressure) coincide with peak tides. Overall, damage is unlikely.
This day’s tides are slightly lower than the 20–21 ft range observed during moderate flooding events, but the barometric pressure does dip below 1000 hPa, which heightens the need for monitoring. Historically, tides under 21 ft paired with pressures near but above 992.8 hPa have not caused major flooding. NOAA indicates a 0% likelihood of flooding, but these conditions are somewhat higher risk than Days 1 and 2—still unlikely to produce flood damage, yet close enough to warrant a Category 3 designation.
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.
