Redondo Beach, WA
CATEGORY 3
WHAT
Tides are expected to peak near 20.4 ft, with moderately low barometric pressure around 1009 hPa. Although NOAA indicates only a low (3.2%) flood likelihood, these conditions are somewhat close to historically observed Category 3 events. Minor flooding in extremely low-lying areas is possible, but significant damage is not anticipated.
WHEN
Highest water levels are likely around late morning through early afternoon on November 8 (around 07:30 AM PST for the peak tide and again in the late afternoon/evening for a secondary high tide).
IMPACTS
• Minor flooding of low-lying roads, parks, and shoreline areas is possible.
• Little to no property damage is expected.
• Brief road closures could occur in the most flood-prone spots.
Barometric pressure remains safely above the historically critical ~992.8 hPa threshold. Wind speeds are low, limiting onshore push. Compared to historical Category 4 events (which often featured stronger winds and somewhat higher tides), current conditions are less severe. Still, the tide height is sufficiently high to merit monitoring, similar to the January 6, 2025 Category 3 event, though NOAA’s flood likelihood is lower this time.
CATEGORY 2
WHAT
Peak tide heights near 20.3 ft are expected, but barometric pressure is higher (~1012 hPa), and NOAA’s flood likelihood is only 1.4%. These conditions suggest no substantial flood risk.
WHEN
Primary concern would be during the morning high tide, around 08:30 AM PST, though minimal impacts are expected.
IMPACTS
• No notable flooding is anticipated.
• Shoreline areas may see typical high-tide water levels but are unlikely to overflow onto roads.
Even though tide heights are similar to those on Day 1, increased barometric pressure and lower NOAA flood likelihood reduce the chance of nearshore flooding. Historically, tides around 20 ft can cause minor inundation if combined with significantly lower atmospheric pressure or high onshore winds, neither of which applies here.
CATEGORY 2
WHAT
Morning tides may reach around 20 ft, with barometric pressure approximately 1014–1016 hPa. NOAA’s flood likelihood (0.3%) remains very low, indicating essentially no flood risk.
WHEN
Peak water levels occur late morning (around 09:30–09:45 AM PST), but no notable flooding issues are expected.
IMPACTS
• No flooding impacts are anticipated.
• Typical high-tide impacts along the shoreline, without overflow risks.
Pressure remains well above critical thresholds. Winds remain modest and not from a direction known to increase surge in this region. Compared to past Category 3–4 events, both pressure and wind factors here are far less conducive to 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; still uncertain about major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
