Redondo Beach, WA
CATEGORY 3
WHAT
Minor coastal flooding is possible. Elevated tide levels are expected but are unlikely to cause significant flood damage.
WHEN
From 6:00 AM to 8:00 AM PST, particularly around the high tide at 7:12 AM PST.
IMPACTS
Potential minor flooding of low-lying areas near shorelines and tidal waterways. Some inundation of beaches and susceptible access roads may occur.
Barometric Pressure: The barometric pressure during the morning high tide is 1019.32 hPa, which is significantly higher than pressures recorded during historical severe flood events. This suggests less severe weather conditions and a lower likelihood of extreme flooding.
Tide Height: The expected high tide is approximately 20.062 ft at 7:12 AM, which is higher than the historical Category 3 event on 12/27/2023 (17.460 ft) but lower than the Category 4 events. This indicates a notable tide but not at a level typically associated with major flooding.
Wind Direction and Speed: Winds are forecasted to be light, around 3-6 kmph (2-4 mph) from the North. This is less extreme than in higher-category events and is unlikely to significantly influence flooding conditions.
NOAA Flood Likelihood: NOAA's flood likelihood is low at 1.1%, with a distance to the flood threshold of -1.12 meters. This indicates a low risk of flooding based on NOAA's assessments.
Comparison with historical events shows that, despite the higher tide levels, the elevated barometric pressure and low wind speeds reduce the potential for significant flooding. Therefore, the flood potential is categorized as Category 3 for Day 1.
CATEGORY 3
WHAT
Minor coastal flooding is possible. High tide levels continue but are unlikely to cause significant flood damage.
WHEN
From 6:30 AM to 8:30 AM PST, particularly around the high tide at 7:54 AM PST.
IMPACTS
Potential minor flooding of low-lying coastal areas, with possible minor inundation of beaches and walkways.
Barometric Pressure: The barometric pressure during the high tide is forecasted at 1012.40 hPa. While slightly lower than Day 1, it remains higher than pressures associated with severe flooding events, indicating less severe conditions.
Tide Height: The expected high tide is approximately 20.084 ft at 7:54 AM, similar to Day 1. This tide height is higher than the historical Category 3 event but still lower than Category 4 events.
Wind Direction and Speed: Light winds are expected, with no significant wind events forecasted. Wind influence on flooding is likely minimal.
NOAA Flood Likelihood: NOAA's flood likelihood is low at 1.3%, with a distance to the flood threshold of -1.08 meters, suggesting a low risk of flooding.
The slightly lower barometric pressure compared to Day 1 warrants monitoring, but overall conditions align with a Category 3 flood potential due to the combination of elevated tide heights and high barometric pressure.
CATEGORY 3
WHAT
Minor coastal flooding is possible. Elevated tide levels persist but are unlikely to cause significant flood damage.
WHEN
From 7:00 AM to 9:00 AM PST, particularly around the high tide at 8:36 AM PST.
IMPACTS
Minor flooding of coastal areas is possible, with minimal impact expected on infrastructure.
Barometric Pressure: The barometric pressure during the morning high tide is forecasted at 1011.13 hPa. While it shows a slight decrease from previous days, it remains well above the levels associated with historical severe flooding events.
Tide Height: The expected high tide is approximately 20.067 ft at 8:36 AM, consistent with the previous days and higher than the historical Category 3 event.
Wind Direction and Speed: Winds remain light, with no significant changes expected. The influence of wind on flooding conditions is minimal.
NOAA Flood Likelihood: NOAA's flood likelihood remains low at 1.0%, with a distance to the flood threshold of -1.15 meters, indicating a continued low risk.
Despite the gradual decrease in barometric pressure, conditions do not align with those of historical severe flooding events. The combination of factors supports a Category 3 flood potential for Day 3.
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.
