Redondo Beach, WA
CATEGORY 3
WHAT
There is a potential for near-flood conditions with relatively high tides (peaking near 18.8 ft). Barometric pressure at the primary high tide windows hovers in the mid- to high-900s hPa, which is slightly lower than normal but not extremely low. This combination places conditions close to a flood event but still unlikely to cause significant damage.
WHEN
Peak concern around early morning (03:30) and late afternoon to early evening (18:06) high tides.
IMPACTS
Minor inundation in the most flood-prone areas is possible (e.g., near shorelines and low-lying spots), but widespread or major damage is not expected.
• The tide height is below 20 ft, which is less than that observed in historical Category 4/5 flood events.
• Barometric pressure is near but not consistently below the 992.8 hPa threshold associated with more severe storm surges.
• Historical comparisons (e.g., 12/27/2023 Category 3 event at ~17.46 ft and moderate pressure) suggest monitoring is warranted, though major impacts are unlikely.
CATEGORY 3
WHAT
Moderately high tides expected (near 19.0 ft max), with barometric pressure readings mainly around 996–1005 hPa during the highest tide periods. Conditions again appear close to, but not definitively at, flood levels.
WHEN
Early morning high tide around 04:00, and evening high tide around 18:42.
IMPACTS
Minor flooding of very low-lying or poorly drained areas is possible. Any impacts are expected to be localized, with no major property damage anticipated.
• Tide levels remain under 20 ft, below typical Category 4 thresholds.
• Barometric pressure is not sufficiently low to indicate a severe storm setup.
• Comparisons to past Category 3 events (tide range ~17–20 ft, moderate pressure) also show consistency with slight but manageable flooding concerns.
CATEGORY 3
WHAT
Elevated tide levels (top near 19.2 ft) and barometric pressure readings around 1005 hPa during key high tide windows. Similar to the prior days, conditions suggest a near-flood scenario that merits attention without high risk of extensive flooding.
WHEN
Peak tide influences around mid-afternoon (14:06) and early evening (19:18).
IMPACTS
Possible water encroachment into the lowest-lying coastal areas, parking lots, and roads adjacent to the shoreline. Widespread inundation or property damage remains unlikely.
• Tides remain below the ~21 ft levels more commonly associated with damaging coastal flooding in the historical record.
• Barometric pressure is well above the ~992.8 hPa threshold that typically exacerbates storm surge risks.
• NOAA CO-OPS data for this period does not indicate notable flood likelihood; historical analogs reinforce a Category 3 assessment.
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.
