MIAMI (AP) — Tropical Storm Colin is bringing the threat of rain and high winds for a day or two during the holiday weekend to both North and South Carolina. Conditions are expected to improve by Monday’s July Fourth celebrations. Separately, the center of Tropical Storm Bonnie rolled into the Pacific on Saturday after a rapid march across Central America, where it caused flooding, downed trees and forced hundreds to evacuate in Nicaragua and Costa Rica. There were no immediate reports of deaths.
