Redondo Beach, WA
CATEGORY 3
WHAT
While widespread flooding is not anticipated, tidal levels on the morning of January 22 (peaking near 20.4 ft around 7:36 AM) are quite high. Barometric pressure remains elevated (around 1022–1023 hPa), lessening the overall flood risk. Despite this, it is close enough to a flood event that monitoring is warranted.
WHEN
Morning high tide from approximately 7:00 AM through 8:30 AM PST.
IMPACTS
Minor flooding in very low-lying areas near the shoreline is possible. Little to no property damage is expected, but watch for pooled water on roadways near the coast.
• Barometric pressure (1022.96 hPa) is significantly higher than in historical moderate flooding events, reducing the potential severity.
• Compared with the 01/06/2025 Category 3 event (tide ~20.68 ft, barometric ~1020.47 hPa, NOAA flood likelihood >11%), the current NOAA likelihood (4.9%) is considerably lower. This supports only minor concerns.
• Winds remain light, limiting onshore push.
CATEGORY 3
WHAT
Tidal heights again reach around 20.4–20.5 ft early on January 23. Barometric pressure remains elevated (roughly 1023–1024.8 hPa). NOAA’s forecast shows a higher (though still moderate) flood likelihood of about 7.9%, indicating we should remain watchful during high tide periods.
WHEN
Overnight high tide around 2:30 AM and a morning tide near 8:00 AM PST pose the greatest concern, particularly 7:00–9:00 AM PST.
IMPACTS
Minor coastal flooding of parks, beaches, and possibly a few low-lying roads. No major property damage is anticipated, but localized issues or short-lived flooding in vulnerable spots could occur.
• Barometric pressure is still much higher than pressures seen in severe floods (e.g., <1002 hPa).
• Historically, a 20+ ft tide with notably lower pressure and higher NOAA flood likelihood (~10% or more) led to Category 4 floods. Here, the combination of stable (high) pressure and moderate NOAA emphasis suggests only minor, short-term flooding potential.
CATEGORY 2
WHAT
Although tidal levels remain around 20.4 ft, the barometric pressure is even higher (about 1028 hPa). NOAA’s forecast for this date indicates only a 3.8% flood likelihood (categorized as “Low”). Consequently, there is essentially no expected flood risk for the 24th despite the high tide level.
WHEN
Primary high tide near 8:30 AM PST, but with minimal likelihood of any flooding.
IMPACTS
No flooding is expected. Low-lying coastal locations remain unaffected aside from routine higher water levels at the immediate shoreline.
• The significantly high barometric pressure, combined with NOAA’s reduced flood likelihood, points to no practical flood threat.
• Even though the tide height is comparable to Days 1 and 2, the mitigating factors (very stable high pressure, calm wind conditions, and a low NOAA percentage) keep flood risk at bay.
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.
