Rina, with maximum sustained winds of 45 mph, was about 195 miles west of Grand Cayman Island moving northwest at 6 mph, the center said in its 11 a.m. EDT advisory. Rina was expected to turn to the west-northwest during the next two days, the center said. The storm\'s center was forecast to pass north of the northeastern coast of Honduras, which has discontinued an earlier tropical storm watch. Rina could produce 1 to 3 inches of rain along the northeast coast of Honduras and 2 to 4 inches of rain could fall over the Cayman Islands. Belize, the east coast of the Yucatan Peninsula and adjacent islands should monitor Rina\'s progress, the hurricane center said.
