Redondo Beach, WA
CATEGORY 3
WHAT: Minor coastal flooding possible. Tide levels may reach up to 20.544 feet, close to flood thresholds for the area.
WHEN: From 6:00 AM to 8:00 AM PST.
IMPACTS: Minor flooding of low-lying areas, parks, and local roads near the shoreline. Isolated road closures are possible.
Barometric Pressure: The mean barometric pressure during the high tide at 7:24 AM is 1034.74 hPa, which is significantly higher than pressures observed during historical flood events (e.g., pressures below 992.8 hPa). High barometric pressure suggests lower likelihood of severe weather conditions contributing to flooding.
Tide Height: The predicted tide height of 20.544 feet is approaching the levels observed in past Category 3 events but remains below the thresholds of more severe events. Historical Category 4 and 5 events had tide heights exceeding 21 feet.
Wind Direction and Speed: Wind data indicates a southerly wind direction with speeds around 5-15 kmph (3-9 mph) during this period. This is less impactful compared to historical events where higher wind speeds and specific wind directions contributed to flooding.
NOAA Flood Likelihood: NOAA's flood likelihood for this date is categorized as "High" with a likelihood percent of 5.2%. However, the distance to the flood threshold is -0.68m, indicating that the tide levels are below the threshold by this margin.
Conclusion: While the tide height is notably high, the elevated barometric pressure and moderate wind conditions reduce the overall flood risk. The situation is close to a flood event and worth monitoring, fitting the criteria for a Category 3 event.
CATEGORY 2
WHAT: No significant coastal flooding expected. Tide levels remain high but are not anticipated to cause flooding.
WHEN: High tide at 8:18 AM PST.
IMPACTS: No significant impacts expected. Normal conditions for shoreline and low-lying areas.
Barometric Pressure: Mean barometric pressure during the high tide is 1020.79 hPa, which is considerably higher than pressures associated with historical flooding events.
Tide Height: Tide levels are predicted to reach approximately 20.339 feet at 8:00 AM, which is lower than the previous day and below historical flood thresholds.
Wind Direction and Speed: Winds are expected to be from the southeast at speeds ranging from 4-16 kmph (2-10 mph). These conditions are typical and not conducive to flooding.
NOAA Flood Likelihood: NOAA's flood likelihood is categorized as "Low" with a likelihood percent of 2.6%, and the tide level is below the flood threshold by -0.82m.
Conclusion: All indicators suggest no risk of flooding for Day 2. The conditions align with a Category 2 classification, representing no substantial flood risk.
CATEGORY 2
WHAT: No significant coastal flooding expected. Tide levels are decreasing, reducing any minimal flood risk.
WHEN: High tide at 9:12 AM PST.
IMPACTS: No significant impacts expected. Normal conditions for coastal and low-lying regions.
Barometric Pressure: The mean barometric pressure is forecasted at 1016.40 hPa during the high tide, still above the critical low-pressure thresholds observed in historical flood events.
Tide Height: Predicted tide levels peak at around 20.061 feet at 9:00 AM, which is lower than previous days and well below historical flood event levels.
Wind Direction and Speed: Winds are expected to be light and variable, predominantly from the southeast at speeds of 6-20 kmph (4-13 mph). No significant wind impact anticipated.
NOAA Flood Likelihood: NOAA categorizes the flood likelihood as "Low" with a likelihood percent of 0.6%. The distance to the flood threshold is -1.1m, indicating ample clearance below critical levels.
Conclusion: The combination of lower tide heights, higher barometric pressure, and minimal wind effects results in no expected flooding. Day 3 is appropriately classified as Category 2, signaling no flood risk.
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.
