Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. The tide is expected to peak near 20.25 ft in the late morning hours, which is higher than many non-flooding events on record, although still below more severe historical flood benchmarks.
WHEN
The main period of concern is around the morning high tide (approximately 9:30 AM to 10:30 AM PST).
IMPACTS
Minor flooding in very low-lying coastal areas may occur. At these levels, flooded spots will generally be limited to shoreline paths and immediate shoreline roads. Property damage is unlikely based on current data.
• The barometric pressure at the highest tide is forecast around 1015.65 hPa, which is not particularly low compared to past severe events.
• NOAA’s flood likelihood sits at about 4.1%, which is lower than historical Category 4 events where likelihood exceeded 10%.
• Winds remain light, reducing the risk that wind-driven waves will exacerbate flooding.
CATEGORY 3
WHAT
Tides will again peak near or just above 20 ft in the late morning, warranting continued monitoring for localized minor flooding. Some spots along the shoreline could see slight water encroachment.
WHEN
Greatest concern is during the late morning high tide (roughly 10:00 AM to 11:00 AM PST).
IMPACTS
Similar to Day 1, minor inundation of low-lying areas near the coast is possible. Widespread flood damage is not expected.
• Barometric pressure is slightly lower (about 1012.3 hPa) than Day 1, but NOAA’s flood likelihood drops to 2.8%, balancing out the risk.
• Historical reference: 12/18/2024 (Category 4) recorded a slightly higher tide and a notably higher flood likelihood, so conditions this time favor a lower severity category.
CATEGORY 2
WHAT
While tides remain elevated (around 20.1 ft), overall flood risk is below threshold levels. This places Day 3 in the “No Substantial Flood Risk” range.
WHEN
High tide concern window is mid-to-late morning (approximately 10:30 AM to 11:30 AM PST).
IMPACTS
No notable coastal flooding impacts anticipated. Only minimal, if any, ponding near the immediate shoreline.
• The barometric pressure is expected around 1016.07 hPa, which is comparatively higher (less conducive to flooding).
• NOAA projects an even lower flood likelihood of around 2.0%.
• This day compares most closely to benign historical high-tide events that did not produce meaningful 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 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.
