Redondo Beach, WA
CATEGORY 3
WHAT
There is potential for minor coastal flooding near the late morning high tide, with water possibly reaching into low-lying shorelines and adjacent roads. Conditions are close to a flood event but significant flood damage is not expected.
WHEN
Peak concern around the high tide window from approximately 8:30 AM to 10:30 AM PST.
IMPACTS
Minor flooding of low-lying parks, road edges, and beach areas. Brief, isolated road closures near the shoreline are possible.
• Tide levels on 12/09/2025 are forecast to reach around 20.55 ft at mid-morning.
• Barometric pressure is expected to remain relatively high (around 1024–1026 hPa), which generally lowers the chance of severe flooding.
• NOAA’s flood likelihood for this date is about 12.1%, which is comparable to previous Category 3 events but with higher pressure than typical Category 4 conditions.
• Winds from the south to southwest at lower speeds (generally under 15 mph) further reduce the possibility of major flooding.
CATEGORY 3
WHAT
A similar scenario of elevated tide levels could bring another period of minor coastal flooding, again unlikely to cause damage but worth monitoring if you live or park in low-lying coastal areas.
WHEN
Highest risk is near mid-morning (around 9:00 AM to 10:30 AM PST).
IMPACTS
Minor flooding of shoreline parks and low-lying roads is possible, including brief standing water along the immediate waterfront.
• The morning high tide on 12/10/2025 is slightly over 20.3 ft.
• Barometric pressure is forecast to be even higher (near 1028–1031 hPa), reducing the likelihood of more severe flood impacts.
• NOAA flood likelihood is lower than Day 1 at about 5.3%, which still indicates the potential for minor issues but not a major event.
• Winds remain moderate and are not from a more flood-prone northwest direction, which helps to keep overall flood risk contained.
CATEGORY 2
WHAT
Tide levels will remain relatively high in the morning hours. However, with very high barometric pressures and a lower NOAA flood likelihood, no flooding issues are expected.
WHEN
Highest tide is late morning (around 10:00 AM to 11:30 AM PST), but minimal risk of coastal flooding is anticipated.
IMPACTS
No significant flooding is forecast. Normal coastal activities and shoreline travel should be unaffected.
• The forecast tide height near midday is approximately 20.07 ft but paired with barometric pressure around 1030+ hPa.
• NOAA indicates only a 1.5% flood likelihood, reflecting minimal threats of flooding.
• Historical data shows similar tides at this pressure level typically remain below action thresholds for coastal flooding.
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.
