Computer models are now tracking Invest 93 and 94 in the Atlantic. While both should be monitored, the one to watch is Invest 94.
Invest 93 (east red area) continues to develop in the central Atlantic as shower and thunderstorm activity associated with the tropical wave continues to show signs of organization. The wave is currently about 750 miles east of the Lesser Antilles.
Environmental conditions are forecast to be favorable for development, and a tropical depression is likely to form during the next couple of days while the system moves west-northwestward to northwestward into the western tropical Atlantic.
The formation chance through 48 hours has increased to 70 percent and the formation chance through 7 days is now 90 percent.
Invest 94 (west red area) is the one to watch. Models are bringing the storm west of Bermuda and too close to the east coast for my liking. These are relatively new model runs and shifting in the path is likely over the next several days.
Located east of the Leeward Islands this tropical wave is producing a large area of disorganized showers, thunderstorms and gusty winds across much of the Windward and Leeward Islands.
This wave is expected to move west-northwestward at 15 to 20 mph, spreading heavy rainfall and gusty winds into Puerto Rico and the Virgin Islands tonight and Wednesday.
The system is then expected to slow down and turn northwestward when it reaches the southwestern Atlantic near the Bahamas late this week, and a tropical depression could form.
The formation chance through 48 hours is now 30 percent and the formation chance through 7 days is up to 70 percent.
Hurricane Gabrielle remains a Category 3 and will remain a major hurricane through Wednesday.
Hurricane Gabrielle was located near latitude 34.3 North, longitude 57.5 West and is moving toward the east-northeast near 20 mph. A faster east-northeastward motion is expected through Thursday.
On the forecast track, the center of Gabrielle will begin approaching the Azores during the day on Thursday and move across the island chain overnight into Friday.
Maximum sustained winds have decreased to near 125 mph with higher gusts.
Gradual weakening is expected during the next couple of days.
Hurricane-force winds extend outward up to 45 miles from the center and tropical-storm-force winds extend outward up to 140 miles.
The estimated minimum central pressure is 953 mb.
Swells generated by Gabrielle will continue to affect Bermuda, the U.S. East Coast from North Carolina northward and Atlantic Canada over the next few days.
