This rainfall will lead to widespread areas of life-threatening and potentially catastrophic flash flooding and mudslides, especially along and near the Sierra La Esperanza. Elsewhere across the rest of Honduras, Belize, El Salvador, eastern Guatemala, western Nicaragua, and the Mexican State of Quintana Roo, Sara is expected to produce 5 to 10 inches of rain with localized totals around 15 inches through early next week.
