Redondo Beach, WA
CATEGORY 3
WHAT
Moderate high tides (peaking near 18–19 ft) coinciding with slightly reduced barometric pressure around 1000.94–1002 hPa. These conditions bring water levels close to minor flood thresholds, though widespread flooding is unlikely.
WHEN
Primary concern around the morning high tide (just after 04:00 AM) and again late afternoon (around 05:00 PM to 06:00 PM).
IMPACTS
• Very isolated minor inundation near low-lying coastal spots could occur.
• Little to no property damage is expected.
• Brief standing water in typical trouble areas (e.g., low beach access points or parking lots).
Comparing with historical events such as 12/27/2023 (Category 3 at 17.46 ft, 1006.1 hPa), Day 1’s slightly higher tide (up to about 18.7 ft) and barometric pressure near 1001 hPa warrant continued monitoring. However, NOAA’s Flood Likelihood for 2025-04-12 is listed as 0%, indicating an overall low risk of significant flooding. Limited wind speeds further reduce the threat but remain watchful around peak tide cycles.
CATEGORY 2
WHAT
Tides remain relatively high (similar to Day 1), but barometric pressure is forecast to be higher (around 1007–1008 hPa). Winds remain light, and NOAA guidance continues to show a 0% flood likelihood.
WHEN
Early morning through midday, with the highest tide near 04:30–05:00 AM and another midday tide around 12:54 PM.
IMPACTS
• No significant flooding is anticipated.
• Normal tidal fluctuations with minimal impacts on shore roads or beach areas.
Although the tide heights approach levels seen in minor flood events, the higher barometric pressure and low flood risk from NOAA data indicate conditions are not expected to escalate. Historically, Category 3 flooding generally involves either lower pressure or higher tidal readings than forecast here. Thus, Day 2 remains comfortably in a no-flood-risk category.
CATEGORY 3
WHAT
Tides once again near the upper range of 18–19 ft, with moderate barometric pressure around 1003 hPa—slightly lower than Day 2, so the risk profile is a bit higher than the previous day but still below major flood thresholds.
WHEN
Highest risk periods around midday (1:00–2:00 PM) and late afternoon/evening (after 5:30 PM).
IMPACTS
• Possible very minor coastal flooding in the most flood-prone areas.
• No significant property damage anticipated, but watch for brief ponding in low-lying spots.
Comparisons to prior Category 3 events (e.g., 12/27/2023) show a similar combination of moderately high water and modestly lowered pressure. NOAA’s Flood Likelihood is 0% for this day, keeping overall concerns relatively low. Light winds also reduce any likelihood of wave-driven 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 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.
