Redondo Beach, WA
CATEGORY 3
WHAT
Minor coastal flooding risk, primarily around the early morning high tide near 06:30 AM, peaking around 20.9 ft. Barometric pressure remains relatively high (about 1024 hPa), which limits storm intensity. NOAA’s flood likelihood is elevated (20.6%), but the higher pressure suggests only minor flooding if it occurs.
WHEN
From around 06:00 AM to 07:30 AM PST. A secondary high tide occurs near 04:24 PM but with similarly high atmospheric pressure, so additional impacts should remain modest.
IMPACTS
• Localized flooding of low-lying beach areas.
• Minor water on coastal roads possible, though closures are unlikely.
Historically, tide heights near 20.7–20.9 ft at or above 1020 hPa have caused close-to-flood conditions (Category 3). Although NOAA’s stated flood likelihood (20.6%) is higher than some past moderate events, the significantly elevated barometric pressure (1024+ hPa) is expected to keep flooding impacts limited. Wind speeds are modest and from the SSE, lessening potential wave-driven inundation.
CATEGORY 4
WHAT
Potential moderate flooding, especially around the morning (07:06 AM) and late afternoon (05:18 PM) high tides, which are expected to climb near or slightly above 20.9 ft. Barometric pressure drops somewhat (down toward 1018 hPa), increasing flood potential compared to Day 1.
WHEN
• Highest risk around 07:00–08:00 AM PST and again 05:00–06:00 PM PST.
IMPACTS
• Flooding of shoreline roads and parking areas is likely, though major property damage remains unlikely.
• Minor disruptions to traffic in low-lying coastal zones.
Compared with Day 1, the lower barometric pressure (1018 hPa) and a continued high NOAA flood likelihood (28.9%) raise overall flood potential. While this is not expected to rise to Category 5 (which historically requires both lower pressure and higher tides above 21 ft), moderate flooding is more likely, warranting Category 4 classification.
CATEGORY 4
WHAT
Moderate coastal flooding likely, centered on early morning (07:42 AM) and early evening (06:18 PM) high tides. Tides again approach 20.9 ft, and barometric pressure around 1011 hPa is sufficiently lower to sustain moderate flood risk.
WHEN
• Peak flood threat from roughly 07:30–08:30 AM PST and again 06:00–07:00 PM PST.
IMPACTS
• Additional flooding of low-lying roads, parks, and residential areas near the coast.
• Minor property impacts in areas directly exposed to rising water at high tide, though major damage is not expected.
Although the tide remains under 21 ft, barometric pressure near 1011 hPa is significantly lower than Days 1–2, aligning with elevated NOAA flood likelihood (24%). Historically, pressures closer to or below 992 hPa plus tides above 21 ft have led to severe flooding (Categories 5–7). Since neither threshold is met, Category 4 (likely flooding without major property damage) is most appropriate.
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.
