Redondo Beach, WA
CATEGORY 2
WHAT
No flood impacts are expected on April 2. Tide levels will be relatively high (peaking near 19.3 ft in the early morning), but barometric pressures around 1011–1015 hPa remain well above the historically significant low-pressure flood thresholds.
WHEN
Highest tides occur late overnight into early morning (around 04:00–05:00 AM), but no flooding is anticipated through the day.
IMPACTS
No practical flooding impacts are expected. Normal daily activities should remain unaffected.
NOAA’s flood likelihood for April 2 is 0.0%, consistent with no risk of flooding. Although the morning tide is comparatively high, the barometric pressure is not low enough to raise concerns. This contrasts with historical Category 3 or higher events, which typically involved lower pressures (under ~1006 hPa) or higher tidal heights above 20 ft.
CATEGORY 2
WHAT
Similar to Day 1, no flooding is expected on April 3. Despite moderate-to-high tides (near 18.5–19 ft) in the morning and evening, the barometric pressure (around 1008–1009 hPa) remains above the critical range associated with flooding.
WHEN
Early morning (around 05:00 AM) and late afternoon to early evening (around 05:00–06:00 PM) correspond to higher tidal periods, yet no flood impacts are anticipated.
IMPACTS
No significant impacts to coastal areas are expected. Normal travel and shoreline activities should continue without interruption.
NOAA’s forecast indicates a 0.0% flood likelihood for April 3. While the pressure is slightly lower than on April 2, it is still not close to the much lower readings associated with past flood events. Winds remain light, reducing the risk of surge or wave-driven flooding.
CATEGORY 3
WHAT
Although NOAA’s overall likelihood remains at 0.0%, barometric pressures are forecast to drop to around 1000–999 hPa during high tide periods on April 4. This lower pressure, combined with tide heights near 18.5–19 ft, brings conditions closer to a flood scenario and warrants monitoring.
WHEN
Highest vigilance is advised early morning (around 05:00–06:00 AM) and again late morning (near 10:00 AM), when the tide and lowered pressure coincide.
IMPACTS
Still unlikely to cause damage, but minor overflow in low-lying or poorly drained coastal areas is possible. Beaches and waterfront walkways may experience brief ponding.
Past Category 3 events often showed somewhat higher tides or more sustained low barometric pressures, but the combination here is enough to categorize this as “close to a flood event and worth monitoring.” Winds do not appear strong, reducing wave action risks. Nevertheless, local authorities and residents in vulnerable spots should stay alert in case of any unexpected tidal surges.
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.
