Redondo Beach, WA
CATEGORY 2
WHAT
High tides approaching 20 feet are expected around midday, but extremely high barometric pressure (approximately 1032–1034 hPa) and light winds greatly reduce the likelihood of overt coastal flooding. NOAA’s forecasted flood likelihood for this date is only 1.3%.
WHEN
Predominantly during the midday high tide window (around 12:00 PM to 1:30 PM PST).
IMPACTS
No flooding is anticipated. Minor ponding could occur in particularly low-lying spots, but no significant road closures or property damage are expected.
Comparing with historical events (such as 12/27/2023, categorized as a Category 3), barometric pressure on Day 1 is significantly higher and NOAA’s flood likelihood is much lower. For these reasons, even though tide heights are relatively elevated, overall conditions are less conducive to flooding.
CATEGORY 2
WHAT
High tides near 19.7–19.8 feet are forecast for the early afternoon. Again, the atmospheric pressure is notably high (up to ~1034.6 hPa) with calm winds. NOAA’s flood likelihood is only 0.2%.
WHEN
Greatest tidal heights occur in the midday to early afternoon (around 1:00 PM PST), though no flood impacts are expected.
IMPACTS
No flooding is predicted. Conditions along the shoreline should remain stable with minimal impact to property or infrastructure.
Previous Category 3–4 events generally included lower barometric pressure levels and higher NOAA flood likelihood readings. The combination of sustained high pressure and light winds here keeps the risk in the no-flood zone.
CATEGORY 3
WHAT
Early morning high tides may exceed 20 feet (peaking near 20.3 ft around 5:00 AM PST) with a moderate barometric pressure (~1021 hPa). While NOAA’s data shows a relatively low flood likelihood of 3.8%, the higher tidal range edges conditions closer to a minor flood event compared to the preceding days.
WHEN
From approximately 4:00 AM to 6:00 AM PST during the highest tides.
IMPACTS
Minor coastal flooding is possible in low-lying or poorly drained areas directly along the shoreline. Inundation is not expected to rise to damaging levels, but residents and businesses close to the water should remain vigilant.
Although the tide height is somewhat comparable to several past moderate flooding events, barometric pressure is still higher and wind speeds are forecast to be relatively light, suggesting that any coastal inundation should be limited. Nonetheless, the peak tide is high enough to justify monitoring.
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.
