Redondo Beach, WA
CATEGORY 3
WHAT
Coastal water levels may approach but are not expected to exceed flood thresholds. Highest tide is around 19.67 ft with moderately low pressure near 999.82 hPa, so there is a possibility of minor coastal ponding, but widespread or damaging flooding is unlikely.
WHEN
Around the high-tide period Saturday evening (near 2025-06-14 20:18).
IMPACTS
• Minor water on low-lying roads and parking lots near the shoreline
• Localized ponding in tidal wetlands or near drainage outfalls
• Little to no property damage expected
• Historical comparison: Similar to past Category 3 events (e.g., 12/27/2023) with tide heights in the 17–20 ft range and moderate atmospheric pressure.
• Winds remain relatively light (under ~10 mph), which lessens storm surge concerns.
• Below the barometric pressure threshold (992.8 hPa) that has historically signaled higher flood risk.
CATEGORY 4
WHAT
Coastal flooding is likely. High tide may reach about 19.72 ft, and the barometric pressure is projected around 993.86 hPa—close to historically low-pressure conditions that have led to moderate flooding in the past.
WHEN
High tide of greatest concern is Sunday evening (near 2025-06-15 20:54).
IMPACTS
• Flooding of normally dry coastal areas, especially where tide and wind setup may combine
• Potential minor inundation of roads and low-lying structures close to shore
• Some property near the immediate waterfront could experience minor flood impacts
• Compared to past events like 01/07/2022 (Category 4) with similar tide heights but slightly lower pressure, conditions here are sufficient to make minor flooding likely.
• Limited wind speeds temper the overall threat somewhat, but pressure remains low enough to raise concern.
• No NOAA flood likelihood data is available, so caution is advised.
CATEGORY 4
WHAT
There is a continued likelihood of coastal flooding, possibly a bit higher risk than Day 2. Tide levels are forecast to peak around 19.77 ft, and barometric pressure may drop as low as ~990.33 hPa, which is below the historical threshold of 992.8 hPa that often correlates with coastal flooding.
WHEN
Most significant risk is Monday evening (near 2025-06-16 21:30).
IMPACTS
• Flooding in areas prone to high-tide inundation, such as low-lying roads and neighborhoods close to the water
• Some minor to moderate property impacts are possible but not expected to be severe or widespread
• Localized road closures or travel disruptions may occur
• Historical parallels: Although tide heights are below the ~21 ft markers of more extreme floods (Category 5 or higher), barometric pressure is notably low and can amplify tidal effects.
• Wind speeds remain moderate; however, any onshore flow could exacerbate water levels.
• No official NOAA flooding likelihood data is provided for these dates, but caution is recommended given the low pressure and high tides.
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.
