FIRST ALERT: Tropical depression likely to form this week
MYRTLE BEACH, SC (WMBF) - While Tropical Depression Nicholas continues to bring torrential rainfall to the Gulf Coast, we continue to focus on multiple chances of development in the tropics.
Showers and thunderstorms associated with a low pressure area located a few hundred miles south-southwest of the Cabo Verde Islands continue to show signs of organization. Environmental conditions are expected to remain conducive for development, and a tropical depression is likely to form within the next couple of days. This system is expected to move westward to west-northwestward across the tropical Atlantic during the next several days. The chance of development remains high at 80% over the next 48 hours and 90% over the next five days.
After development, this will be a system we need to keep an eye on. While it’s still a ways away, models continue to take this toward the lesser Antilles by early next week.
A broad area of low pressure located a few hundred miles northeast of the central Bahamas is producing a large area of disorganized showers and thunderstorms. Environmental conditions appear marginally conducive for development, and a tropical depression is likely to form during the next couple of days while the system moves north-northwestward to northward off the southeast U.S. coast. Regardless of development, this system could bring high surf to portions of the southeast and mid-Atlantic U.S. coasts later this week. The chance of development remains at 60% over the next two days and then increases to 70% over the next five days.
A tropical wave is expected to emerge off the west coast of Africa in a day or two. Thereafter, environmental conditions are forecast to be conducive for development while the system moves generally west-northwestward to northwestward over the far eastern Atlantic. The chance of development remains low at 20% over the next five days.
