As expected, Tropical Depression #16 was officially designated this morning for the low we've been watching in the northwest Caribbean south of Cuba. TD 16 is just below Tropical Storm strength, and will likely reach that later today or tomorrow and be named Nicole. This system is expected to track over Cuba and southern Florida tomorrow, then hug along the Southeast US Thursday. Heavy rain is possible in the Commonwealth from late Wednesday through Thursday while this system interacts with the surface boundary that will stall along the coast today. This is the front moving through today associated with the potent low pressure system tracking north of us this morning.
