Redondo Beach, WA
CATEGORY 3
WHAT
Tide levels near 20.75 ft around mid-morning coincide with moderate onshore winds. Barometric pressure remains high (~1025 hPa), keeping conditions from escalating into a major flood event. Overall, this is close to a flood event and worth monitoring, but unlikely to cause structural or property damage.
WHEN
Highest risk near the morning high tide, approximately 6:30 AM to 8:30 AM PST, peaking around 7:42 AM.
IMPACTS
• Possible minor pooling of water in very low-lying areas
• Minimal to no impact on most roadways and structures
NOAA indicates around a 9.6% flood likelihood for today, labeled “High” in their scale, but the elevated barometric pressure historically correlates with reduced flooding potential. Compared to past Category 4 events (e.g., 12/18/2024) that combined a similar tide height with lower pressure and higher winds, conditions today are less severe, aligning more closely with a Category 3 based on historical benchmarks.
CATEGORY 3
WHAT
Morning high tide near 20.65–20.70 ft under very high barometric pressure (~1027 hPa). NOAA’s flood likelihood remains listed as “High” at 7.9%, but given strong pressure and moderate winds, widespread flooding is unlikely.
WHEN
Highest risk around the morning high tide, roughly 7:00 AM to 9:00 AM PST, peaking near 8:12 AM.
IMPACTS
• Localized water on shore-adjacent paths or parking areas
• Little or no threat to property damage
Similar to Day 1, conditions are near the threshold for minor coastal flooding but do not approach the lower pressure profiles found in more serious flood events. Historically, a similar tide (20.68 ft) with a lower barometer than we see now was classified as Category 3 (01/06/2025). That precedent supports maintaining Category 3.
CATEGORY 2
WHAT
A peak tide around 20.40 ft occurs in the morning hours, though NOAA’s forecast shows a much lower (2.7%) flood likelihood. Barometric pressure near 1020 hPa is not particularly low. Given these factors, no significant flooding is expected.
WHEN
Morning high tide from about 7:30 AM to 9:30 AM PST, peaking near 8:48 AM. Another high tide occurs late evening but remains below thresholds of concern.
IMPACTS
• Essentially no flood impacts anticipated
• Standard caution in typical low spots, but property damage risk is minimal to nonexistent
While the tide height remains higher than normal, it does not surpass 21 ft, and the barometric pressure is not low. Historical events with similar conditions have shown negligible flooding, aligning with a Category 2 classification (i.e., no real risk of 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.
