Redondo Beach, WA
CATEGORY 2
WHAT
No significant flooding is anticipated. Elevated tides will reach approximately 19.1 ft early in the morning. Barometric pressure is forecast around 1013.9 hPa, which is well above the historically low thresholds that have led to coastal flooding in the past.
WHEN
Highest tide near 4:12 AM.
IMPACTS
• No flooding of homes or businesses is expected.
• Minor over-wash in very low-lying spots near the shoreline is possible, but no measurable impact is anticipated.
• NOAA’s Flood Likelihood stands at 0.0% for this date, aligning with the higher barometric pressure readings.
• Historically, flood risks have been more pronounced above 21 ft tide height coupled with notably lower pressure (e.g., near or below ~992 hPa). Current conditions remain well within safe parameters.
CATEGORY 2
WHAT
Once again, no major flooding concerns. The highest tide is projected near 19.3–19.4 ft in the early morning, with a barometric pressure around 1014.3 hPa. A slightly lower afternoon tide (around 16 ft) aligns with a modest drop in pressure to about 1008.4 hPa, but that pressure is still not low enough to raise flood concerns based on historical patterns.
WHEN
Primary high tide near 4:30 AM, second high tide mid-afternoon around 4:30 PM.
IMPACTS
• Coastal roads and properties are unlikely to face flooding.
• Low-lying areas may experience minor ponding or over-wash, but this should not result in damage.
• NOAA reports a 0.0% flood likelihood for March 18.
• Although the afternoon pressure is relatively lower, it remains substantially higher than the ~992 hPa benchmarks observed during Category 4 or 5 flood events in the past.
CATEGORY 2
WHAT
Tides may reach around 19.6 ft early in the morning. Barometric pressure readings around 1015 hPa are still considered moderate and do not align with conditions that have led to substantial coastal flooding in historic events.
WHEN
Highest tide near 5:00 AM, secondary high tide late afternoon around 5:00 PM.
IMPACTS
• Minimal to no property impact; typical beach areas should remain unaffected.
• Minor pooling possible in extremely low-lying spots, but no material flood risk is anticipated.
• NOAA continues to report 0.0% flood likelihood.
• In prior Category 3 or higher events, tide heights exceeded 20 ft alongside much lower barometric pressures (below ~1006–992 hPa). Current conditions remain distinctly safer.
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 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
