Redondo Beach, WA
CATEGORY 3
WHAT Conditions will approach a minor coastal flood scenario, primarily due to an early morning tide near 18.4 ft coinciding with notably low barometric pressure around 992 hPa. While actual flooding is not guaranteed, water levels may get close to minor flooding thresholds in very low-lying areas.
WHEN Highest risk near the early morning high tide (around 03:00–03:30 AM PDT) and again during the late afternoon/evening high tide period.
IMPACTS No major impacts are anticipated. However, there is the potential for minor flooding of parking areas, boat ramps, and low-lying spots along the shore.
NOAA’s Flood Likelihood Analysis indicates a “Low” risk (0% likelihood), but a relatively high tide above 16 ft combined with low barometric pressure suggests conditions will be close to a minor flood event. The wind speeds forecast (generally less than 10 mph) are lower than in past Category 4 events, which helps keep the overall risk below major flood thresholds. Compared to historical events (such as 01/07/2022, Category 4, with higher tide of 19.255 ft and stronger winds), this forecasted event is less intense.
CATEGORY 2
WHAT Tides are forecast around the mid- to upper-18 ft range, but barometric pressure will be higher than on Day 1 (approximately 995–998 hPa). This reduces concerns for tidal flooding.
WHEN Mainly during the late afternoon high tide period (around 18:00–19:00 PM PDT).
IMPACTS No significant flooding is expected. Areas prone to typical high-tide ponding may see minor water accumulation, but widespread issues are not anticipated.
NOAA’s data continues to show a 0% flood likelihood, and no strong onshore winds from the W/NW are forecast. Overall conditions indicate a more stable scenario than Day 1, with higher atmospheric pressure alleviating flood potential. Compared to previous coastal flood events reaching Category 3 or 4, Day 2’s tide heights remain below more serious thresholds.
CATEGORY 2
WHAT Though the tide may briefly approach 19 ft, barometric pressure remains well above the historically low levels typically associated with severe coastal flooding (forecast around 997 hPa). Thus, conditions do not support significant flooding.
WHEN Flood risk (if any) would be highest late in the day near the evening high tide (around 18:30–19:00 PM PDT).
IMPACTS No noteworthy flooding impacts are anticipated. Low spots along the shoreline could experience minor water intrusion typical of elevated evening tides.
As with prior days, NOAA’s official Flood Likelihood Analysis remains at 0%. While tides do rise near 19 ft, they remain below the 20–21 ft benchmark more commonly associated with moderate or higher flood categories. Light winds and relatively stable atmospheric trends also limit coastal flood potential.
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.
