Redondo Beach, WA
CATEGORY 4
WHAT
A moderate coastal flood risk is likely, primarily due to a forecast high tide peaking near 19.35 feet around 8:18 PM local time. Barometric pressure at that time is expected to be approximately 994.3 hPa, which is notably lower than typical summer values and could enhance tidal effects.
WHEN
Peak concern from late afternoon into the evening hours (roughly 5:00 PM to 9:00 PM).
IMPACTS
• Flooding of low-lying roads near the waterfront is likely.
• Some minor water encroachment into parking areas or parks adjacent to the shoreline is possible.
• Major property damage is not expected at this water level.
Historical comparisons point to the 01/07/2022 Category 4 event, which also featured a tide near 19 feet combined with barometric pressure below 1000 hPa. Although NOAA’s official likelihood percentages remain at 0.0%, the relatively low barometric pressure means local caution is warranted during the evening high tide.
CATEGORY 3
WHAT
Conditions approach a minor-to-moderate flooding threshold but are less concerning than Day 1. While the evening tide could again near 19 feet, the barometric pressure around 1001.7 hPa is higher, reducing the overall risk of flood impacts.
WHEN
Highest risk around the evening high tide (approximately 8:00 PM to 9:00 PM).
IMPACTS
• Tidal overflow points may see brief standing water.
• Only isolated or very minor issues in low-lying areas are expected.
NOAA’s Flood Likelihood remains at 0.0% for the date. Though the maximum tide is relatively high, the increased pressure compared to Day 1 moderates the potential impacts. Wind forecasts also indicate primarily N or NNW flow, which typically does not exacerbate tidal surges in Redondo Beach compared to strong onshore (W/NW) winds.
CATEGORY 3
WHAT
Close to flood levels again, but overall risk stays moderate, with high tide cresting near the upper 18- to 19-foot range and barometric pressure around 999.6 hPa.
WHEN
Greatest concern near the high tide window in the evening (roughly 8:30 PM to 9:30 PM).
IMPACTS
• Temporary flooding of very low-lying roadways and beach parking lots.
• No major structural damage anticipated.
Even though barometric pressure is lower than normal (999.6 hPa), present guidance and historical patterns (for example, 12/27/2023’s Category 3 event with tides around 17.46 ft) suggest only minor to moderate flood effects. NOAA continues listing flood likelihood at 0.0%.
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.
