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:

Day 1 (2024-08-16):

Given the high barometric pressure and moderate tide heights, the flood potential is categorized as Category 2 (Minor coastal flooding).

Day 2 (2024-08-17):

Similar conditions as Day 1 with high barometric pressure and moderate tide heights lead to a Category 2 (Minor coastal flooding).

Day 3 (2024-08-18):

The slightly lower barometric pressure combined with higher tide heights increases the flood potential to Category 3 (Moderate coastal flooding).


This analysis is based on the provided data and historical comparisons, emphasizing barometric pressure as a critical factor in flood risk assessment. Always consult local authorities for final decision-making in flood-related situations.
