The tropics are heating up again, with forecasters monitoring four systems in the Atlantic on Friday morning (Sept. 21). Two of the systems could become depressions at the beginning of next week.
It is still too early to say where systems can go as they grow, but they pose no immediate threat to the earth.
On the National Hurricane Center's five-day forecast map, the shaded areas show where tropical depressions could form. Shaded areas are not prediction tracks, which are normally issued when the storm gets stronger or is about to turn into a depression.
Here's what we know about systems starting at 7 am from the National Hurricane Center.
60% chance of development
A tropical wave off the African coast lies about 600 miles southeast of the Cabo Verde Islands and travels west at a speed of 15 to 20 mph across the Atlantic.
The storms associated with it show signs of organization and forecasters claim that conditions are conducive to slow development.
A tropical depression could form early next week as the system moves west across the Atlantic. It is unlikely (20%) to develop at least one tropical depression with 48 hours and an average chance (60%) to develop within five days.
The categories of cyclones, increasingly strong, are tropical depression, tropical storms and hurricanes.
Cyclone should form
A low pressure system is expected to develop Friday night over the Atlantic Ocean between Bermuda and the Azores.
Conditions should be favorable for the acquisition of subtropical or tropical low characteristics, and a subtropical or tropical cyclone should form late.
at the weekend or early next week as the bass winds over the central Atlantic Ocean.
A "cyclone" is the generic term that encompasses depression, storm and hurricane.
The system has a 70% chance of becoming a tropical depression within five days.
Slow development possible
A wide area of low pressure is located just southeast of Bermuda and moves south at a speed of 10 to 15 mph.
Environmental conditions could result in slow development by the middle of next week, during the crossing of the Southwest Atlantic Ocean.
He has a low chance (20%) of development in a tropical depression with five days.
Low pressure zone
A low low pressure zone is about 600 miles east of the Windward Islands. It is moving to the west at 10 mph.
The showers associated with it are not organized and the system should not develop further. It is unlikely (10%) to turn into a tropical depression at least within 48 hours.
