Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected. Although the early-morning high tide (around 03:36) will approach 19 feet, the barometric pressure is not low enough to raise concern of coastal flooding, and NOAA’s flood likelihood for the day remains at 0%.
WHEN
Highest tide occurs around 03:36 and again in the mid-afternoon around 15:48, but neither is expected to produce flood impacts given current atmospheric conditions.
IMPACTS
No significant coastal flooding is anticipated. Shorelines and low-lying areas should remain free of water inundation.
• Tide heights near 19 feet can sometimes approach minor flood stages when combined with lower barometric pressure (below ~992 hPa), but here the Mean Sea Level pressure is around 998–1002 hPa.
• Historical Category 3 events have typically involved near- or above-20 ft tides and lower pressures.
• NOAA CO-OPS indicates 0% flooding likelihood for this day, consistent with Category 2 (no risk) conditions.
CATEGORY 2
WHAT
No risk of flooding. Morning high tide near 03:54 rises to around 18.9 feet, with pressure above 1001 hPa. Afternoon high tide is lower and likewise not expected to cause any coastal flooding.
WHEN
Early morning (03:54) and mid-afternoon (16:36). No heightened flood concerns anticipated during these times.
IMPACTS
No notable impacts to coastal roads, parks, or homes.
• Compared to past Category 4 or 5 events, these tides remain below the typical flooding threshold, and mean sea level pressure is significantly higher than dangerous levels (<992.8 hPa).
• NOAA continues to project a 0% flood likelihood for 2025-04-11.
CATEGORY 2
WHAT
No risk of flooding. The highest tide (near 04:12) reaches about 18.8 feet, but barometric pressure remains around or above 1004 hPa.
WHEN
Early morning (04:12) and later afternoon (17:18).
IMPACTS
No flooding impacts are expected.
• Although tides near 19 feet can warrant closer attention, the pressure is well above the historical low-pressure triggers for flood concerns.
• NOAA flood likelihood again sits at 0% for this date, matching Category 2 conditions (no 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.
