Redondo Beach, WA
CATEGORY 3
WHAT
A pair of relatively high tides (peaking near 03:06 AM around 18.4 ft) will coincide with notably low barometric pressure (approximately 992.12 hPa). Although the pressure is quite low, NOAA indicates a 0.0% flood likelihood. These factors place conditions near a flood event threshold, but significant flooding is not anticipated.
WHEN
Highest risk near the early morning (around 03:06 AM) and again late afternoon (around 17:30 PM) during peak tides.
IMPACTS
Mostly minor impacts, if any. Low-lying shoreline areas could experience brief standing water or wave splash-over, but no meaningful property damage is expected.
Compared with historical events, this tide height is moderate (some Category 3 events in the past involved tide heights in the 17–20 ft range). While the barometric pressure here is similarly low to previous higher-category storms, the tide does not exceed about 20 ft, which reduces the overall flood risk. NOAA’s probability assessment also supports a low chance of flooding.
CATEGORY 2
WHAT
Tides will again reach elevated levels (near 18.8 ft), but barometric pressures (around 994.46–997.7 hPa) are higher than Day 1, and NOAA continues to indicate a 0.0% flood likelihood.
WHEN
Key high tides occur early morning (around 03:30 AM) and early evening (near 18:06 PM).
IMPACTS
No overt flooding impacts are expected. Low-lying coastal areas may see typical high-tide conditions, but there is no indication of hazardous inundation.
In comparison with past moderate flood events, these tides remain below the historically higher thresholds (19–20+ ft) that led to minor flooding. With barometric pressure trending higher and NOAA data showing no concern, any flooding risk is minimal.
CATEGORY 3
WHAT
Tides may reach around 19.0 ft later in the day (peaking near 18:42 PM) under moderately low barometric pressure (approximately 995.67 hPa). While still below the more significant 20+ ft levels seen in some Category 4 events, the tide height is higher than Day 1 and Day 2. NOAA’s forecast remains at a 0.0% flood likelihood, suggesting only a small chance of notable flooding.
WHEN
Early morning tide (roughly 04:00 AM) and a late-afternoon/evening tide (18:42 PM) present the highest water levels.
IMPACTS
Possible minor standing water or splashing in very low-lying areas along the shoreline. No property damage is anticipated; conditions should be monitored but are unlikely to escalate.
Historically, tides around 19–20 ft can approach borderline flood conditions if paired with very low pressure. Although the pressure is somewhat low, NOAA’s flood model indicates minimal risk. These conditions align most closely with prior Category 3 events.
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.
