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 these factors, the flood potential is categorized as Category 2 due to relatively high barometric pressure and moderate tide heights.

Day 2 (2024-08-17):

Similar conditions as Day 1 lead to a Category 2 flood potential due to high barometric pressure and moderate tide heights.

Day 3 (2024-08-18):

The slightly lower barometric pressure combined with higher tide heights increases the flood potential to Category 3 for this day.


This analysis provides an informed forecast based on available data but should be supplemented by local authorities' guidance for final decision-making in flood-related situations.
