Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is anticipated. Tides may reach around 19 ft in the afternoon, but barometric pressure remains relatively high (~1018 hPa). NOAA’s flood likelihood is reported at 0.0%, indicating no expectation of coastal flooding.
WHEN
Highest tide near 3:00 PM local time on 09/17.
IMPACTS
No significant impacts expected. Normal tidal fluctuations will occur, but no coastal flooding issues are forecast.
On this day, the tide is elevated but still below 21 ft, and the barometric pressure is well above 992 hPa. These factors, combined with NOAA's low flood likelihood assessment, do not support flood conditions. Historically, Category 4 and higher events require substantially lower barometric pressures plus tides exceeding 20 ft. In this case, conditions are much less severe.
CATEGORY 2
WHAT
No risk of flooding is anticipated. Afternoon high tide again hovers around 19 ft, with a barometric pressure near 1015–1019 hPa. NOAA continues to show a 0.0% likelihood of flooding in the region.
WHEN
Highest tide near mid-afternoon on 09/18.
IMPACTS
No notable flooding impacts or damage are expected at these levels.
While the tide remains somewhat high compared to average, barometric pressure is not sufficiently low to indicate significant concerns. Previous Category 3 or 4 events showed notably lower pressures or higher tide levels. As such, current data aligns with no flood risk.
CATEGORY 2
WHAT
No risk of flooding is anticipated despite another high tide approaching 19 ft. The barometric pressure, although somewhat lower (~1012 hPa), is still not near the historical low thresholds associated with coastal flood events. NOAA’s flood likelihood remains at 0.0%.
WHEN
Highest tide near mid-afternoon on 09/19.
IMPACTS
No significant impacts are expected. Coastal waters could appear higher than normal but are unlikely to encroach on roads or low-lying properties.
Although the pressure is lower than on Days 1 and 2, it is still not in the range that historically corresponds with flood conditions, particularly since tides are below 21 ft. Analyses of past flood events show that very low barometric pressures (well below ~1000 hPa) plus higher tides are usually needed to produce noticeable inundation.
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.
