Redondo Beach, WA
CATEGORY 4
WHAT
Moderate coastal flooding is likely. Tides will reach approximately 20.7 ft midmorning and again in the early evening. Despite the relatively high barometric pressure near 1026 hPa, the NOAA flood likelihood is elevated (17.1%), suggesting enough surge potential to bring minor to moderate flooding along low-lying shorelines.
WHEN
Highest risk during the morning high tide (around 8:18 AM PST) and again near the evening high tide (around 7:24 PM PST).
IMPACTS
Possible minor flood inundation near shoreline areas, parking lots, and low-lying roads. While widespread property damage is not expected, brief road closures or standing water in poor drainage areas are possible.
• The tide height is comparable to previous Category 4 events, though the barometric pressure is higher than in many of those historical floods.
• NOAA’s elevated flood likelihood (17.1%) balances the dampening effect of high pressure, leading to a forecast of Category 4 conditions.
• Winds remain mostly from the S/SW at moderate speeds, not adding significantly to coastal water push from the west.
CATEGORY 4
WHAT
Moderate coastal flooding remains likely, with tides reaching around 20.5 ft. Barometric pressure drops to near 1011.8 hPa around the morning high tide. NOAA’s flood likelihood (9.3%) still rates as “High,” indicating a continued risk of minor to moderate flooding.
WHEN
Most concern around high tide in the morning (approximately 8:48 AM PST) and again during the evening high tide (around 8:30 PM PST).
IMPACTS
Minor roadway flooding in low-lying areas and near the waterfront is possible. Some parking lots and beach access roads could experience brief closures. Property damage is not expected to be widespread.
• Although the NOAA percentage (9.3%) is a bit lower than Day 1, the barometric pressure is also lower, slightly increasing flood vulnerability at times of high tide.
• Historical Category 4 events with similar tide levels and moderate barometric pressure have produced moderate coastal flood impacts, aligning with this forecast.
CATEGORY 3
WHAT
Close to a minor flood event, but unlikely to cause notable damage. Tides will peak around 20.2 ft in the late morning. NOAA indicates a lower flood likelihood (2.2%), reflecting reduced flood potential compared to the prior days.
WHEN
Primary window of concern accompanies the morning high tide (around 9:24 AM PST) and a secondary peak in the evening (near 9:54 PM PST).
IMPACTS
While sustained inundation is not expected, there could be brief ponding of water along the immediate shoreline, particularly in areas with poor drainage. Significant damage is unlikely.
• The barometric pressure (about 1016 hPa) is moderate, and NOAA categorizes the overall risk as “Low” compared to the two previous days.
• Tide levels remain high enough to merit monitoring, but the combination of conditions does not strongly favor flooding beyond minor water accumulation.
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.
