Barometric pressure

The city is situated in a low-lying coastal area. It is surrounded by water on three sides: Lake Pontchartrain to the north, Lake Borgne to the east, and the Gulf of Mexico to the south. This unique geography contributes to the low pressure system.

The surrounding lakes and the Gulf of Mexico bring warm, moist air into the city. This warm air collides with the cooler air from the north, resulting in a constant battle of air masses. This clash affects the barometric pressure, keeping it relatively low.

The low-lying terrain also contributes to the development of low-pressure systems. Cold fronts from the north move slowly over the flat land, causing the air to rise and cool. This results in the formation of low-pressure systems, which often bring rain and storms to the city.
