Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected. While the high tide levels will approach notable heights near 19.7 ft, barometric pressure around 1008 hPa remains well above the low-pressure thresholds observed in more severe historical floods. NOAA’s Flood Likelihood for this date is reported at 0.0%, indicating minimal concern.
WHEN
Primary high tide of interest around 8:00-8:30 AM and again near 8:00-8:30 PM local time.
IMPACTS
No significant coastal flooding impacts anticipated. Shorelines and low-lying areas should remain unaffected based on current data.
• Compared to past events categorized at higher levels (Category 3 or above), today’s expected barometric pressure is not sufficiently low, and NOAA’s official flood likelihood is 0%.
• Wind direction is mostly south/southwest at moderate speeds, differing from the westerly or northwesterly winds that have historically contributed to notable tidal surges.
• The 12/17/2022 (and similarly 12/27/2022) high-tide flood events had significantly lower barometric pressures (well under 992 hPa) and higher confirmed flood likelihood data. Those conditions are not present here.
CATEGORY 2
WHAT
Again, no risk of flooding is expected. Tidal heights may reach approximately 19.4 ft, but barometric pressures near 1008–1009 hPa do not indicate an approaching storm surge. NOAA’s flood likelihood remains at 0.0%.
WHEN
Peak tidal levels primarily mid-morning (around 9:00-9:45 AM) and late evening (near 8:30-9:00 PM).
IMPACTS
No significant impacts to coastal roadways or low-lying neighborhoods are expected.
• Historical Category 3 or 4 floods typically involved pressures closer to or below ~1002 hPa with tides rising beyond 20 ft. These conditions are not met here.
• NOAA’s official forecast for 2025-08-15 again rates flood risk as low, with no immediate concerns for property damage or inundation.
CATEGORY 2
WHAT
No risk of flooding. Tides approach 19.0 ft during the late evening, but the barometric pressure of ~1008 hPa is similar to the previous days, and winds remain modest.
WHEN
Highest tide in the late evening, around 8:30-9:30 PM local time, with elevated water levels also mid-morning.
IMPACTS
No observed or forecast conditions indicate meaningful inundation of low-lying areas.
• Yet again, NOAA’s official outlook shows 0.0% flood likelihood.
• Winds continue southerly and moderate, differing from the westerly or northwesterly patterns that have historically elevated tidal flooding risk.
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.
