Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 6:00 PM to 9:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be above the threshold that historically indicates severe flooding, reducing the likelihood of a major flood event. However, the high tide at 6:18 AM with a pressure of 1001.81 hPa and another high tide at 8:48 PM with a pressure of 1007.78 hPa, combined with the wind direction from the northwest, could lead to minor coastal flooding. The NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this date, which aligns with the historical data suggesting that while conditions are present for minor flooding, a major event is unlikely.
CATEGORY 2
WHAT Low risk of coastal flooding. Normal tidal conditions expected.
WHEN Throughout the day.
IMPACTS No significant impacts expected. Standard precautions for typical high tide events should be sufficient.
The barometric pressure remains relatively stable and above critical thresholds, indicating no significant weather disturbances that could lead to flooding. The high tide at 7:00 AM has a mean pressure MSL of 1004.17 hPa, and the high tide at 11:48 AM has a mean pressure MSL of 1005.48 hPa, both well above the threshold associated with historical flood events. NOAA's Flood Likelihood Analysis supports this assessment with a low likelihood prediction for this date.
CATEGORY 4
WHAT Elevated risk of coastal flooding due to higher tides and lower barometric pressure.
WHEN High tide events around midday and late afternoon are most concerning.
IMPACTS Potential for moderate flooding in vulnerable areas, including property damage in low-lying regions near the shoreline.
On this day, the barometric pressure drops closer to concerning levels with readings around 999.46 hPa during high tides at both midday and late afternoon. This pressure is closer to historical Category 4 events but still not as low as those associated with Category 5 events. The NOAA Flood Likelihood Analysis maintains a low likelihood rating; however, given the lower pressures at high tides, there is an increased risk compared to the previous days. Residents should remain vigilant and monitor updates closely.
Residents 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. Consult local authorities or experts for final decision-making in flood-related situations and adhere to any advisories or evacuation orders that may be issued.
