Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding. Although tides near 19.4 ft will coincide with moderately lower pressure around 1000–1002 hPa, NOAA indicates a 0.0% likelihood of coastal flooding.
WHEN
Highest tides are expected around 3:42 AM and 4:54 PM PDT on 9/7.
IMPACTS
No significant flooding concerns. No road closures or property impacts anticipated.
Compared to historical flood events (which typically feature tides above 21 ft and significantly lower barometric pressure below 992 hPa), these conditions do not meet the thresholds necessary for coastal flooding. The official NOAA forecast supports no risk.
CATEGORY 2
WHAT
No risk of flooding. Tides reaching about 19.6 ft will coincide with higher barometric pressure near 1006 hPa. NOAA again forecasts a 0.0% flood likelihood.
WHEN
Peak high tides around 4:30 AM and 5:18 PM PDT on 9/8.
IMPACTS
No expected flooding in coastal or low-lying areas.
Though tide heights are somewhat elevated, they remain under the 21 ft mark seen in past flooding. Barometric pressure remains too high to significantly boost flood risk.
CATEGORY 2
WHAT
No risk of flooding. Tides could reach approximately 19.8 ft, but barometric pressure remains around 1008 hPa, well above the critical low-pressure range.
WHEN
Highest tides near 5:24 AM and 5:48 PM PDT on 9/9.
IMPACTS
No known or anticipated flooding impacts.
Even though Day 3’s tide is the highest of the three days, the pressure remains relatively high, and NOAA reports 0.0% flood likelihood. Past severe flood events typically involve lower pressures (<992 hPa) and higher tidal levels above 21 ft.
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.
