Redondo Beach, WA
CATEGORY 2
WHAT
No significant coastal flooding is expected. Model data indicate the morning high tide will approach but remain below the 21 ft threshold at roughly 20.14 ft, and the barometric pressure is relatively high around 1025 hPa.
WHEN
Primary high tide of interest occurs near 05:54 AM PST.
IMPACTS
No flooding impacts are expected; low-lying areas along the immediate shoreline should remain unaffected.
• Barometric pressures for Day 1’s peak tide are significantly higher than those in notable past flood events, reducing likelihood of severe conditions.
• NOAA’s flood likelihood estimate is only about 1.7%, which aligns with no observed flood risk.
• Historically, pressure near or below 992.8 hPa paired with tides over 21 ft is typically needed for more serious coastal flooding; those factors are not met on Day 1.
CATEGORY 2
WHAT
No risk of flooding is anticipated. Tides will be slightly higher than Day 1 but remain below the critical 21 ft threshold, and the barometric pressure remains even higher than on Day 1.
WHEN
Primary high tides of interest occur near 06:18 AM PST and 04:42 PM PST.
IMPACTS
No flooding impacts are forecast; conditions are not expected to pose a threat to coastal or low-lying areas.
• The highest tide approximates 20.37 ft in the early morning, paired with a barometric pressure near or above 1027 hPa, keeping coastal flood risk minimal.
• NOAA’s flood likelihood estimate is 3.6% for Day 2, still low.
• Compared to historical Category 3 or 4 events, both the tide level and barometric conditions are less conducive to flooding.
CATEGORY 3
WHAT
Coastal water levels will be close to a flood event threshold and should be monitored. Although likely not high enough to cause notable property damage, the tide is the highest of the three days.
WHEN
Peak tide occurs near 06:42 AM PST with a tide level around 20.58 ft.
IMPACTS
Minor flooding in very low-lying or poorly drained areas is possible but not expected to be widespread.
• NOAA’s flood likelihood increases to 8.6% on Day 3, labeled “High” by their reporting, but barometric pressure (near 1029 hPa) remains well above the low-pressure thresholds historically associated with damaging floods.
• Historical comparison: a previous Category 3 event on 01/06/2025 reached 20.68 ft with lower barometric pressure (1020.47 hPa). While our tide height is almost as high, the much higher pressure this time limits the intensity.
• Winds are primarily from the south, not from the W/NW where onshore flow can exacerbate 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.
