Redondo Beach, WA
CATEGORY 2
WHAT
No significant flooding is expected. Tide heights (peaking near 18.6 ft) are below the historic flood thresholds, and barometric pressure is relatively high (around 1017–1022 hPa). NOAA’s flood likelihood is 0.0%.
WHEN
Highest tides expected near 11:36 AM and 09:36 PM local time.
IMPACTS
No notable inundation is foreseen. Low-lying coastal areas are unlikely to experience anything beyond routine, very minor water coverage at the shoreline.
Historical Category 3 or above events have typically involved lower barometric pressures (near or below 1006 hPa) and/or tidal heights above 20 ft. These conditions are not present on 10/29, supporting a Category 2 (no risk) assessment.
CATEGORY 2
WHAT
No flooding risk anticipated. Projected peak tide is ~18.8 ft with barometric pressure still well above critical levels (approximately 1020–1022 hPa). NOAA continues to give a 0.0% flood likelihood for this date.
WHEN
Highest tides forecast near 12:24 PM and 11:12 PM local time.
IMPACTS
Minimal or no coastal flooding. Low elevations should remain unaffected given the relatively high pressure and only moderate tidal heights.
Reviewing historical Category 4 and 5 floods reveals both significantly lower pressure and higher tides (often above 20 ft). Given the stable pressure and NOAA’s low-likelihood prediction, Category 2 (no risk) is the most accurate designation.
CATEGORY 2
WHAT
Still no notable flooding risk despite a slightly higher tide near 19.0 ft. Barometric pressure (around 1015 hPa) remains above the historically significant low-pressure thresholds. NOAA’s official outlook remains at 0.0% flood likelihood.
WHEN
Highest tides around 04:48 AM and 01:00 PM local time.
IMPACTS
No substantial flooding concerns. Low-lying areas along the coast are expected to remain dry, with no road closures attributable to tidal inundation.
Although the tidal height on 10/31 is higher than on the preceding days, it is still below levels associated with past Category 3 (or higher) events, especially given the moderate barometric pressure. These factors support a Category 2 classification.
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.
