Redondo Beach, WA
CATEGORY 1
WHAT No risk of flooding is expected. The atmospheric conditions and tide levels indicate normal conditions with no expected inundation.
WHEN No flood risk expected for today.
IMPACTS No impacts anticipated.
Step 1: Assess Barometric Pressure - The barometric pressure during the high tides is approximately 1021.65 hPa and 1021.84 hPa, which is significantly higher than the critical threshold of 992.8 hPa observed in historical flood events. High pressure suggests stable atmospheric conditions and a lower likelihood of severe weather.
Step 2: Evaluate Tide Height - The tide heights at the times of high tide are 18.987 feet (at 05:54) and 18.363 feet (at 16:12). These values are lower than the tide heights recorded during historical Category 4 and 5 flood events, which exceeded 19 feet.
Step 3: Consider Wind Direction and Speed - Wind speeds are modest, ranging from 8 to 9 mph, with a wind direction from the SSW (approximately 200 degrees). This is not a direction known to significantly contribute to coastal flooding in this area.
Step 4: Integrate NOAA High Tide Flooding Likelihood - NOAA's forecast indicates a Low Flood Likelihood with a 0.0% chance of flooding for 2024-11-02. The distance to the flood threshold is -2.18 meters, indicating that water levels are well below levels of concern.
Conclusion: Given the high barometric pressure, moderate tide heights, and lack of significant wind factors, there is no substantial risk of flooding on 2024-11-02. The day is categorized as Category 1, reflecting normal conditions with no expected flood impacts.
CATEGORY 1
WHAT No risk of flooding is expected. Atmospheric and tidal conditions remain within normal ranges without any anticipated inundation.
WHEN No flood risk expected for today.
IMPACTS No impacts anticipated.
Step 1: Assess Barometric Pressure - The barometric pressure during the morning high tide is approximately 1018.75 hPa, which remains well above the critical threshold associated with increased flood risk. This suggests stable weather conditions.
Step 2: Evaluate Tide Height - The tide height at the morning high tide (06:36) is approximately 19.274 feet. While slightly higher than the previous day, it remains below the levels seen in historical Category 4 and 5 events.
Step 3: Consider Wind Direction and Speed - Wind speeds are very low, around 2 mph, with wind directions from the ESE to SSW. These conditions are not conducive to exacerbating flood risks.
Step 4: Integrate NOAA High Tide Flooding Likelihood - NOAA forecasts a Low Flood Likelihood with a 0.0% chance of flooding for 2024-11-03. The distance to the flood threshold is -1.95 meters, indicating safe water levels.
Conclusion: Despite a slight increase in tide height, the continued high barometric pressure and minimal wind influence result in no significant flood risk for 2024-11-03. The day is categorized as Category 1, indicating no expected flood impacts.
CATEGORY 2
WHAT No significant risk of flooding is expected. Slightly higher tides and moderate winds are forecasted, but conditions do not indicate potential for flooding.
WHEN No flood risk expected for today.
IMPACTS No impacts anticipated.
Step 1: Assess Barometric Pressure - The barometric pressure during the morning high tide (around 07:00) is approximately 1019-1020 hPa, which is significantly higher than the historical flood event pressures. High pressure reduces the risk of severe weather conditions that contribute to flooding.
Step 2: Evaluate Tide Height - The tide height reaches approximately 19.384 feet at 07:00, which is comparable to the lower range of historical Category 4 events. However, without accompanying low barometric pressure, the risk remains low.
Step 3: Consider Wind Direction and Speed - Wind speeds increase to 13 mph, with wind coming from the S (around 175 degrees). While higher than previous days, these wind conditions alone are not sufficient to significantly elevate flood risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood - NOAA predicts a Low Flood Likelihood with a 0.0% chance of flooding for 2024-11-04. The distance to the flood threshold is -1.78 meters, keeping water levels within safe limits.
Comparison with Historical Events: - Historical Category 4 and 5 events combined high tide heights over 21 feet with low barometric pressures below 992.8 hPa. The current conditions lack the critical combination of both high tide and low pressure necessary for significant flood risk.
Conclusion: Given the moderate increase in wind speed and tide height, but sustained high barometric pressure, the flood risk remains low for 2024-11-04. The day is categorized as Category 2, reflecting normal conditions with no substantial flood risk expected.
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.
