FLORIDA, United States, Monday September 14, 2015 – Meteorologists are watching three disturbances, one of which could become a tropical depression today or tomorrow and later develop into Tropical Storm Ida.
The system, Invest93L, located several hundred miles west-southwest of the Cape Verde Islands is showing signs of organization, the National Hurricane Centre (NHC) said.
“Environmental conditions are expected to be conducive for development, and this system is likely to become a tropical depression during the next day or two while it moves generally northwestward across the central tropical Atlantic,” it said, giving the disturbance an 80 per cent chance of developing in the next 48 hours and a 90 per cent chance of development over the next five days.
The depression could develop further into the ninth named storm of the Atlantic hurricane season, Ida.

There are two other areas under watch.
One is an area of low pressure located over the southwestern Gulf of Mexico. The NHC says some slow development of this system is possible during the next couple of days while it moves little. After a couple of days, a slow west-northwestward motion toward Mexico is expected and land interaction should limit development, forecasters say.
An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system this afternoon, if it becomes necessary.
Chances of formation through the next 48 hours and next five days are low – 20 per cent and 30 per cent respectively.
The other weather system is a tropical wave located just off the west coast of Africa, which is producing disorganized showers and thunderstorms.
The NHC said conditions are conducive for it to gradually develop during the next several days, while it moves westward at 10 to 15 miles per hour.
