Flood Watch

Redondo Beach, WA

DayInfo1: Day 1: October 25, 2024

CATEGORY 2

WHAT No coastal flooding is expected. Normal tidal conditions are anticipated.

WHEN Throughout the day.

IMPACTS No significant impacts are expected.

ADDITIONAL DETAILS...

Step 1: Assess Barometric Pressure

The barometric pressure is 1033.23 hPa, which is significantly higher than the pressures observed during historical flood events (below 1002 hPa). This high pressure indicates stable atmospheric conditions, reducing the likelihood of severe weather-related flooding.

Step 2: Evaluate Tide Height

The tide height peaks at approximately 18.744 ft at 12:54 PM. While this is higher than the Category 3 historical event (17.460 ft), it is still below the levels associated with significant flooding (over 21 ft). Without accompanying low barometric pressure, the elevated tide height alone does not pose a flood risk.

Step 3: Consider Wind Direction and Speed

Wind speeds are low, ranging from 2 to 5 mph, primarily from the NNE (15 to 31 degrees). These calm wind conditions are not expected to contribute to increased tidal impact or coastal flooding.

Step 4: Integrate NOAA High Tide Flooding Likelihood

NOAA's forecast indicates a low flood likelihood at 0%, suggesting minimal risk for flooding events.

Step 5: Synthesize Information and Forecast Flood Category

Considering the high barometric pressure, moderate tide heights, negligible wind influence, and NOAA's low flood likelihood, the flood potential is categorized as Category 2, indicating no risk of flooding.


DayInfo2: Day 2: October 26, 2024

CATEGORY 2

WHAT No coastal flooding is expected. Normal tidal conditions are anticipated.

WHEN Throughout the day.

IMPACTS No significant impacts are expected.

ADDITIONAL DETAILS...

Step 1: Assess Barometric Pressure

The barometric pressure remains relatively high at 1027.39 hPa during peak tides, still well above thresholds associated with historical flooding events.

Step 2: Evaluate Tide Height

The highest tide reaches approximately 18.796 ft at 12:54 PM, similar to Day 1's tide levels. This height is below the critical level of 21 ft necessary to significantly increase flood risk when paired with low barometric pressure.

Step 3: Consider Wind Direction and Speed

Wind speeds vary between 2 and 9 mph, with directions shifting but generally remaining calm. These wind conditions are insufficient to exacerbate tidal effects or contribute to flooding.

Step 4: Integrate NOAA High Tide Flooding Likelihood

NOAA continues to indicate a low flood likelihood at 0%, reinforcing the assessment of minimal flood risk.

Step 5: Synthesize Information and Forecast Flood Category

Given the stable barometric pressure, moderate tide heights, low wind speeds, and NOAA's low flood likelihood, the flood potential remains at Category 2, indicating no risk of flooding.


DayInfo3: Day 3: October 27, 2024

CATEGORY 2

WHAT No coastal flooding is expected. Normal tidal conditions are anticipated.

WHEN Throughout the day.

IMPACTS No significant impacts are expected.

ADDITIONAL DETAILS...

Step 1: Assess Barometric Pressure

The barometric pressure decreases to 1015.40 hPa but remains above the critical threshold (below 1002 hPa) associated with significant historical flooding events.

Step 2: Evaluate Tide Height

The tide height peaks at approximately 18.953 ft at 2:12 PM, slightly higher than previous days yet still below the critical 21 ft level required to elevate flood risk when combined with low pressure.

Step 3: Consider Wind Direction and Speed

Wind speeds are low, around 2 to 5 mph, coming from the SSW (195 to 209 degrees). These mild winds are not expected to have a substantial impact on tidal conditions or flood risk.

Step 4: Integrate NOAA High Tide Flooding Likelihood

NOAA's forecast maintains a low flood likelihood at 0%, indicating a continued minimal risk of flooding.

Step 5: Synthesize Information and Forecast Flood Category

Despite the slight decrease in barometric pressure, the combination of moderate tide heights, low wind speeds, and NOAA's low flood likelihood supports a flood potential of Category 2, indicating no risk of flooding.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
