Redondo Beach, WA
CATEGORY 2
WHAT No risk of flooding expected. Normal conditions anticipated near shorelines and low-lying areas.
WHEN Throughout the day on 2024-12-31.
IMPACTS No significant flooding impacts expected.
Step 1: Assess Barometric Pressure - The barometric pressure is 1014.22 hPa, which is significantly higher than pressures associated with historical flooding events. This indicates stable atmospheric conditions and a lower risk of flooding.
Step 2: Evaluate Tide Height - The tide height reaches up to 20.245 ft at 06:30 AM, which is below the critical threshold of 21 ft that, when combined with low pressure, significantly increases flood risk. Compared to historical events, this tide height is lower than those associated with flooding.
Step 3: Consider Wind Direction and Speed - Wind speed is low at 1 km/h from the SW (219 degrees). Low wind speeds and this wind direction are not contributing factors to increased flood risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood - NOAA flood likelihood data for this date is not indicating significant risk.
Step 5: Synthesize Information and Forecast Flood Category - Considering the high barometric pressure, tide heights below critical thresholds, low wind speeds, and lack of significant NOAA flood likelihood, the flood potential for this day is categorized as Category 2, indicating no risk of flooding.
CATEGORY 3
WHAT Conditions are close to a flood event; monitoring is advised, but flooding is unlikely to cause damage.
WHEN Around high tide at 06:54 AM.
IMPACTS Minor water level rise in low-lying areas possible; no significant impacts anticipated.
Step 1: Assess Barometric Pressure - The barometric pressure is 1020.77 hPa, higher than pressures observed during historical flooding events. This suggests stable weather conditions and reduces the likelihood of flooding.
Step 2: Evaluate Tide Height - The maximum tide height is 20.399 ft at 06:54 AM, which is significant but still below the 21 ft threshold associated with flooding in combination with low pressure. It is higher than the tide height during the historical Category 3 event but lower than those in higher category events.
Step 3: Consider Wind Direction and Speed - Wind speed is moderate at 5 km/h from the S (181 degrees). This wind speed and direction are not likely to contribute significantly to flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood - NOAA's flood likelihood for this date is High, with a likelihood percent of 5.0%, and a distance to threshold of -0.76 m. While this indicates some potential for flooding, it is lower than the flood likelihood percentages observed during historical Category 3 and Category 4 events.
Step 5: Synthesize Information and Forecast Flood Category - Despite NOAA indicating a high flood likelihood, the high barometric pressure, tide heights below critical thresholds, and moderate wind conditions suggest that flooding is unlikely to cause damage. Therefore, the flood potential is categorized as Category 3, indicating conditions are close to a flood event and worth monitoring, but unlikely to cause flood damage.
CATEGORY 3
WHAT Conditions are close to a flood event; monitoring is advised, but flooding is unlikely to cause damage.
WHEN Around high tide at 07:00 AM.
IMPACTS Minor water level rise in low-lying areas possible; no significant impacts anticipated.
Step 1: Assess Barometric Pressure - The barometric pressure is 1021.97 hPa, which is higher than historical flood event pressures, indicating stable weather and a low likelihood of severe flooding conditions.
Step 2: Evaluate Tide Height - Tide height peaks at 20.426 ft at 07:00 AM. This is slightly higher than on previous days but still below the critical 21 ft threshold needed for a significant flood risk when combined with low pressure.
Step 3: Consider Wind Direction and Speed - Wind speed is low at 3 km/h from the ENE (71 degrees). These conditions are not conducive to increasing flood risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood - NOAA's flood likelihood is High with a likelihood percent of 5.8% and a distance to threshold of -0.73 m. This is slightly higher than on Day 2 but still lower than historical events that led to higher flood categories.
Step 5: Synthesize Information and Forecast Flood Category - Given the high barometric pressure, tide heights below critical levels, low wind speeds, and NOAA's moderate flood likelihood, the flood potential is categorized as Category 3. Monitoring is advised, but significant flooding is unlikely.
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.
