Redondo Beach, WA
CATEGORY 2
WHAT
No substantial flood risk is anticipated. Tides will reach around 19.8 ft, but the barometric pressure remains relatively high (around 1009–1014 hPa), and NOAA indicates a 0.0% flood likelihood.
WHEN
The highest tides of the day occur near the early morning (around 03:00–04:00) and late afternoon (around 17:00).
IMPACTS
No flooding concerns based on current data. Low-lying areas and shorelines are not expected to experience inundation.
Compared with past Category 3 events (e.g., 12/27/2023 with a lower 17.46 ft tide but 1006.1 hPa pressure), these Day 1 conditions do not reach a point of concern. NOAA’s official flood likelihood is effectively zero, reinforcing a Category 2 (no flood risk) outlook.
CATEGORY 3
WHAT
Close to a flood event due to higher-than-normal tides (near 19.8+ ft) and a notably lower barometric pressure (around 996 hPa in the evening), but still unlikely to result in flood damage.
WHEN
The highest tidal risk period occurs early in the morning (around 04:00) and again late in the afternoon through early evening (notably around 18:00) on 4/28.
IMPACTS
While no major flooding is anticipated, brief and minimal water intrusion into extremely low-lying areas or very close to shorelines may be possible. Widespread impacts are not expected.
Historically, Category 3 reflects being “close to a flood event.” Tides are somewhat lower than certain historical Category 4 instances (e.g., 20.586 ft, 12/18/2024), and pressure is not as low as typical Category 4 events (<= 992.8 hPa). NOAA reports 0.0% flood likelihood for this date, suggesting that any coastal impacts remain minimal.
CATEGORY 3
WHAT
Close to a flood event due to a tide approaching ~19.95 ft and moderately low barometric pressure (~994 hPa), but with NOAA still indicating a low chance (0.1%) of actual flooding.
WHEN
Focus on the late afternoon and evening hours (peaking near 19:00) on 4/29, when tides and lower pressure may combine.
IMPACTS
Minor coastal impacts near shorelines and other immediate waterfront spots could occur, but significant flooding or property damage is not expected.
Although the tide is substantial and the pressure is lower than the previous two days, the observed levels remain below the more severe historical flooding benchmarks (e.g., above 21 ft combined with barometric pressure < 992.8 hPa). NOAA data for 4/29 indicates a 0.1% flood likelihood, consistent with Category 3, meaning “worth monitoring” but still unlikely to cause damage.
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; uncertain if it causes major property damage.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
