Redondo Beach, WA
Below is the three-day coastal flood outlook based on the provided weather data, tide forecasts, barometric pressure readings, and NOAA’s flood likelihood analysis. All times are in local time (PST/PDT).
CATEGORY 3
WHAT
High tides will reach approximately 19.0 ft near 03:18, with barometric pressure around 1001.51 hPa. Although this is not exceptionally low pressure, it is still worth monitoring given the relatively high tide. NOAA’s forecast indicates a 0.0% flood likelihood for this day.
WHEN
The highest flood potential is around the early morning high tide window (roughly 02:30–04:00).
IMPACTS
• Minor splash-over possible in very low-lying shoreline areas.
• No major property damage anticipated.
Winds are light (2–4 mph) and do not appear likely to exacerbate water levels. Historically, flood events in this area have typically involved much lower barometric pressure and/or higher tides (above ~20 ft). While tide levels will be elevated, the moderate pressure and calm wind reduce the threat of significant flooding.
CATEGORY 3
WHAT
Overnight high tides will again be near 19.0 ft (peak around 03:36) with a barometric pressure near 998.12 hPa—somewhat low but not below critical thresholds. Later afternoon high tide approaches about 17.3 ft with pressure rebounding above 1002 hPa.
WHEN
Main window of interest is near the early morning tide (03:00–04:30).
IMPACTS
• Minor flooding could affect some very low-lying areas.
• No significant property damage is expected.
NOAA’s flood likelihood remains at 0.0%. Past Category 4 or 5 events generally featured more extreme conditions (tide heights above 20 ft or pressures below ~992.8 hPa). Winds may briefly gust around mid-day, but sustained wind speeds remain moderate and from less critical directions (SW/SSW).
CATEGORY 3
WHAT
Predicted morning high tide of around 18.9 ft at 03:54, with barometric pressure near 1002.58 hPa. Although elevated, neither the tide nor the pressure readings suggest a high probability of damaging flooding. Afternoon high tide (about 16.6–17.0 ft) occurs with similarly moderate pressure.
WHEN
Greatest concern timeframe is around 03:30–05:00.
IMPACTS
• Minor water encroachment in typical low coastal spots.
• Unlikely to cause road closures or notable damage.
Once again, NOAA’s flood outlook indicates a 0.0% likelihood of flooding. Historical comparisons show that significantly lower pressures (<992 hPa) and higher tide peaks (>20 ft) have been more frequently associated with property-damaging floods. Winds remain generally under 15 mph from W/NW or variable directions.
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 major damage would occur.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
