Redondo Beach, WA
CATEGORY 2
WHAT
No coastal flooding is expected on March 25. Despite tides rising to around 18.6 ft in the early morning hours, these levels remain below the 21 ft threshold typically associated with flood risk.
WHEN
Higher water levels will occur around the early morning high tide (02:48 AM), but no flooding impacts are anticipated at any time during this day.
IMPACTS
• No flooding is expected.
• Shoreline areas should not experience inundation.
• Minimal or no roadway impacts anticipated.
Barometric pressure for the early morning high tide is around 1002 hPa, which is not exceptionally low (historically, pressures closer to or below 992.8 hPa combined with tides over 21 ft have led to flooding). NOAA’s flood likelihood forecast stands at 0.0%, further supporting no flood risk.
CATEGORY 2
WHAT
No coastal flooding is expected on March 26. Tides may reach approximately 19 ft early in the morning (around 03:12 AM) when the barometric pressure briefly dips to near 997.5 hPa—still above the critical low threshold for concern.
WHEN
The highest tide occurs in the early morning hours. There is no anticipated flooding throughout the day or evening.
IMPACTS
• No flooding in low-lying coastal areas.
• No anticipated travel disruptions.
Even though the pressure is somewhat lower than on Day 1, the tide height remains under 21 ft and NOAA’s official guidance continues to indicate a low flood likelihood (0.0%). Comparisons to past Category 4 or 5 events show that those required significantly lower pressures (near or below 992.8 hPa) and tide heights above 21 ft.
CATEGORY 2
WHAT
No coastal flooding is expected on March 27. Tides could approach about 19.3 ft. However, barometric pressure is forecast around 1014 hPa, well above the level typically associated with notable flood events.
WHEN
The highest tide occurs in the early morning (around 03:36 AM) and again mid-afternoon (around 15:00 PM). No flooding is forecast at either tide cycle.
IMPACTS
• Conditions remain benign, with no predicted flooding.
• Low-lying coastal communities should remain unaffected by tidal waters.
Historical Category 3 or higher flood events in this area generally combined tide heights exceeding 20 ft (often closer to 21+ ft) with notably lower barometric pressure. NOAA’s official flood likelihood remains at 0.0%, confirming no risk of tidal flooding.
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 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
