Orange-level warning for freezing rain "5:07 AM EDT Wednesday 11 March 2026 Impact Level: High Forecast Confidence: High Significant freezing rain event expected today. What: Prolonged period of freezing rain. Possibly up to 24 hours for some areas. Ice accretion or build up of 10 to 20 mm. When: Beginning early this morning and lasting through tonight.
