Redondo Beach, WA
CATEGORY 2
WHAT
Tides will rise into the mid-to-upper 17-foot range, combined with relatively high barometric pressure (1023–1025 hPa) and mostly southerly winds. No significant flooding is anticipated.
WHEN
Highest tide levels are expected around late evening on March 7th (19:30), coinciding with a mean sea level pressure of approximately 1025 hPa.
IMPACTS
No notable flooding impacts expected. Coastal walkways and very low-lying areas may see minor ponding or elevated water levels but should remain well below flood thresholds.
• NOAA Flood Likelihood is reported as 0% for this date, indicating very low flood potential.
• Compared to historical Category 3 or higher events (which typically involve tide heights near or above 20 ft and much lower barometric pressure), conditions remain well below significant flood risk thresholds.
CATEGORY 2
WHAT
Mid- to upper 18-foot high tides are forecast, with barometric pressure staying around the 1020–1025 hPa range. Minimal threat of coastal flooding.
WHEN
A notable high tide will occur early in the morning around 02:00 and another midday around 11:00. Both occur under higher pressure, reducing any flood threat.
IMPACTS
Low-lying coastal spots may experience slightly elevated water but are unlikely to have any disruption to roads or property.
• NOAA’s Flood Likelihood remains at 0% for March 8.
• Historically, Category 4 or 5 events required tide levels over 20 ft coupled with much lower barometric pressure (<1002 hPa). Current conditions do not approach these criteria.
CATEGORY 2
WHAT
Tides could reach around 19 ft in the early morning (~03:00) and midday (~12:30). Barometric pressure dips as low as ~1011 hPa, but this is still well above the threshold that typically contributes to significant flooding.
WHEN
Watch the morning and midday high tides. Even though pressure is somewhat lower than Days 1-2, it remains significantly above the historical low-pressure benchmarks for flood events.
IMPACTS
No substantial flooding is expected. Property damage remains unlikely, and any minor coastal impacts should be confined to typical high-tide waterline fluctuations.
• NOAA continues to indicate 0% flood likelihood for March 9.
• Compared with the historical Category 4 or 5 floods—which saw tides of 19–22 ft accompanied by pressures around or below 992 hPa—these forecasted pressures are comparatively high, mitigating the chance of flood.
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.
