Redondo Beach, WA
CATEGORY 3
WHAT High tides reaching around 19.65 ft overnight and moderate-to-low atmospheric pressure (around 997 hPa) will bring water levels close to minor coastal flood thresholds, but significant flood damage is unlikely.
WHEN From approximately 01:00 AM through 02:00 AM local time, with a secondary high tide mid-afternoon that appears slightly lower.
IMPACTS Minor flooding of low-lying roads and walking paths is possible, particularly near the shoreline. Routine caution is advised, but major property impacts are not expected.
• Barometric pressure is not forecast to drop below ~997 hPa, keeping conditions less severe than in historically significant floods.
• Tide height compares with past Category 3 events (e.g., 12/27/2023, 01/06/2025), suggesting a close-to-flood scenario that bears watching but is unlikely to escalate into major flooding.
CATEGORY 3
WHAT Tides peaking near 19.80 ft in the late afternoon will lead to water levels slightly below typical flood thresholds. Barometric pressure is around 1005 hPa, which is higher than would typically trigger severe coastal impacts.
WHEN Primary elevated tide occurring from about 04:00 PM to 06:00 PM local time.
IMPACTS Some ponding in low-lying areas, but widespread flooding is not expected. Minor beach erosion or short-term submersion of beach walks is possible.
• Winds remain relatively light, reducing the chance of wind-driven coastal flooding.
• Historically, tides in the high 19-ft range combined with moderate pressure align well with past Category 3 outcomes, warranting monitoring rather than expecting major damage.
CATEGORY 3
WHAT A slightly higher tide around 20.13 ft during early evening hours could bring water very close to minor flood levels; however, atmospheric pressure remains near 1003 hPa, not low enough to strongly amplify flooding.
WHEN Between approximately 05:30 PM and 07:30 PM local time for the highest water levels.
IMPACTS Localized spills onto walkways or parking areas at the immediate coastline are possible, but property damage is unlikely. Drivers in shoreline areas should watch for shallow water on roads.
• While the tide is above 20 ft, it remains below the more serious threshold of ~21 ft often linked with Category 4-5 flooding.
• Comparisons to past Category 3 events indicate conditions are similar in tide height and only moderately low in barometric pressure, limiting the overall flood threat.
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.
