Answer:
Explained below.
Step-by-step explanation:
I think that in order to provide advanced weather warning you need to first have knowledge of Earth's prevailing wings and of the general direction of a track of a low-pressure system and the amount of wind shear and steering currents are needed to accurately predict the direction of a Hurricane. These depend on the location and strength of high and low-pressure systems. Katrina changed direction because the area between 30 and 35 degrees north is known as the horse latitudes. This is where subtropical highs are located. Jet streams can be found over these highs. Katrina probably was steered by one of these. Jet streams are also associated with tornadoes which are probably why hurricanes in these areas spawn tornadoes.
