Redondo Beach, WA
CATEGORY 3
WHAT
The tide on November 10th is forecast to reach around 20 ft during the morning high tide, which is relatively high compared with non-flooding events. Although NOAA’s flood likelihood is still very low (0.3%), this tide height is close enough to previous moderate events to warrant keeping an eye on local conditions. However, because barometric pressure is expected to be around 1018 hPa—well above historical low-pressure flood events—and winds are forecast to be light, significant flooding is unlikely.
WHEN
Peak risk near the high tide, approximately 9:00 AM to 10:00 AM PST.
IMPACTS
• While some minor nuisance flooding in extremely low-lying spots or along the immediate shoreline cannot be completely ruled out, no major property damage is expected.
• Local roads that are right at the water’s edge could experience brief standing water, but widespread road closures are not anticipated.
• Historical Category 3 events often had lower barometric pressure and higher NOAA flood likelihood percentages. This event features higher pressure (about 1018 hPa) and a much smaller chance (0.3%) of flooding according to NOAA.
• The tide height of ~20 ft is indeed high, but in the absence of strong onshore winds or significantly lower pressure, major flooding is unlikely.
• Comparison with past Category 3 floods suggests this scenario is worth monitoring but should not cause significant impacts.
CATEGORY 2
WHAT
On November 11th, tides are expected to peak around 19–20 ft. Barometric pressure readings range from ~1018 hPa in the morning high tide to around 1010 hPa later in the evening. Although this pressure is a bit lower than on Day 1, it is not near the historically critical low-pressure thresholds (close to or below 992.8 hPa). NOAA’s flood likelihood remains very low, at 0.1%.
WHEN
Highest tidal range during late morning (around 10:30 AM PST) and again in the late evening (around 8:30–9:00 PM PST).
IMPACTS
• No notable coastal flooding or property impacts are expected.
• Shoreline roads and particularly low-lying areas could see some ponding of water, but conditions should not approach flood thresholds.
• Tides do not reach the 21 ft benchmark often associated with more substantial concerns.
• Winds remain relatively light and primarily from the south, reducing the usual wind-driven surge risk.
• NOAA’s minimal likelihood forecast also reinforces a low flood potential.
CATEGORY 2
WHAT
The forecasted tides for November 12th peak close to 19.5 ft, with barometric pressure around 1012 hPa for the midday high tide. While there is a period of slightly lower pressure (near 1009 hPa) overnight, the tidal heights remain below more critical flooding thresholds, and NOAA assigns a 0.0% flood likelihood.
WHEN
Peak tide in the late morning hours (around 10:30–11:30 AM PST).
IMPACTS
• No flooding impacts are expected.
• Mariners and those near shorelines may notice higher-than-normal tide levels, but coastal inundation and property impacts should be minimal to nonexistent.
• Even with moderate rainfall potential, the barometric pressure remains far from historically low storm conditions.
• The absence of strong winds from the west or northwest further lessens typical wave run-up or storm surge concerns.
• Overall conditions align more closely with non-flooding historical patterns.
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.
