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.

Forecast Reasoning:

Step-by-step analysis for each day:

DayInfo1 (2024-08-18):

  1. Assess Barometric Pressure:
  2. High tide at 02:18 AM: Pressure = 1009.67 hPa
  3. High tide at 05:00 PM: Pressure = 1011.91 hPa

  4. Both pressures are significantly higher than the critical threshold (992.8 hPa), indicating less severe weather conditions.

  5. Evaluate Tide Height:

  6. High tide at 02:18 AM: Tide height = 18.137 ft
  7. High tide at 05:00 PM: Tide height = 19.320 ft

  8. These heights are lower than the Category 3 event (17.460 ft) but not as extreme as Category 4 or Category 5 events.

  9. Consider Wind Direction:

  10. Wind direction predominantly from the south (S) and south-southeast (SSE), which historically has less impact on exacerbating flood conditions in this region.

  11. Integrate NOAA High Tide Flooding Likelihood:

  12. NOAA's forecast indicates a low likelihood of flooding for this date.

  13. Synthesize Information:

  14. Given the higher barometric pressure and moderate tide heights, the flood category for this day is predicted as Category 2, indicating minor coastal flooding potential.

DayInfo2 (2024-08-19):

  1. Assess Barometric Pressure:
  2. High tide at 03:12 AM: Pressure = 1016.15 hPa
  3. High tide at 05:24 PM: Pressure = 1018.04 hPa

  4. Both pressures are significantly higher than the critical threshold (992.8 hPa), indicating less severe weather conditions.

  5. Evaluate Tide Height:

  6. High tide at 03:12 AM: Tide height = 18.504 ft
  7. High tide at 05:24 PM: Tide height = 19.597 ft

  8. These heights are lower than the Category 3 event (17.460 ft) but not as extreme as Category 4 or Category 5 events.

  9. Consider Wind Direction:

  10. Wind direction predominantly from the south-southeast (SSE), which historically has less impact on exacerbating flood conditions in this region.

  11. Integrate NOAA High Tide Flooding Likelihood:

  12. NOAA's forecast indicates a low likelihood of flooding for this date.

  13. Synthesize Information:

  14. Given the higher barometric pressure and moderate tide heights, the flood category for this day is predicted as Category 2, indicating minor coastal flooding potential.

DayInfo3 (2024-08-20):

  1. Assess Barometric Pressure:
  2. High tide at 04:06 AM: Pressure = 1017.43 hPa
  3. High tide at 05:54 PM: Pressure = 1015.94 hPa

  4. Both pressures are significantly higher than the critical threshold (992.8 hPa), indicating less severe weather conditions.

  10. Wind direction predominantly from the south-southeast (SSE), which historically has less impact on exacerbating flood conditions in this region.

  11. Integrate NOAA High Tide Flooding Likelihood:

  12. NOAA's forecast indicates a low likelihood of flooding for this date.

  13. Synthesize Information:

  14. Given the higher barometric pressure and moderate tide heights, the flood category for this day is predicted as Category 2, indicating minor coastal flooding potential.

This analysis provides an overview based on current data trends and historical comparisons, emphasizing that while minor coastal flooding is possible, it is unlikely to cause significant damage or disruption under these conditions.
