Redondo Beach, WA
CATEGORY 2
WHAT
No risk of coastal flooding is anticipated. Despite tides reaching around 18.8 ft at midday, barometric pressure remains relatively high, reducing the potential for significant flood effects.
WHEN
Highest tide is expected midday on 10/30 (approx. 12:24 PM).
IMPACTS
No notable flooding impacts forecast. Low-lying roads and shorelines are unlikely to experience inundation.
• Barometric Pressure ~1021.87 hPa at peak tide — significantly higher than the low-pressure scenarios that historically contributed to coastal flooding (e.g., Category 4–5 events).
• NOAA data indicates a 0.0% flood likelihood for this date, aligning with minimal observed risk.
• Wind speeds are relatively light and not from a direction that historically increases flood potential.
• Compared to historical Category 3 and above events, the tide heights are lower and the pressure is substantially higher, reinforcing a Category 2 assessment (no flood risk).
CATEGORY 2
WHAT
No risk of flooding is forecast. Tides may rise to around 19 ft, but barometric pressure is not low enough to enhance flood risk.
WHEN
Highest tide near 1:00 PM on 10/31 (around 19.06 ft), under ~1012.22 hPa.
IMPACTS
No flooding concerns expected; normal beach activity should remain unaffected.
• While the tide inches higher than Day 1, the barometric pressure (1012 hPa) remains well above the critical low thresholds seen in major flooding events.
• NOAA flood likelihood remains at 0.0%.
• Historical Category 3 events typically had either lower pressure (<1006 hPa) or notably higher flood-likelihood indicators; these conditions are absent here.
CATEGORY 2
WHAT
No risk of flooding persists. Though tide peaks may approach roughly 19.3 ft in the early afternoon, atmospheric pressure is expected to stay moderate.
WHEN
Highest tide around 1:30 PM on 11/01, barometric pressure approx. 1014.69 hPa.
IMPACTS
No measurable flooding or impacts on coastal infrastructure anticipated.
• Pressure remains above 1014 hPa, well above the more concerning sub-1000 hPa levels.
• NOAA’s posted flood likelihood is again 0.0%.
• Compared with Category 4–5 historical floods (where tide heights exceeded 20 ft alongside much lower barometric pressure), current conditions are significantly 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; damage uncertain.
• Category 5: Likely to flood with property damage.
• Categories 6-7: Extreme risk of flooding and property damage.
