Parts of North Florida were blanketed by snow on Tuesday as a winter storm barreled through the South, resulting in the first-ever blizzard warning along parts of the Gulf Coast in Texas and Louisiana.

There are reports of snow already in Pensacola as of late Tuesday morning. Florida Gov. Ron DeSantis issued a state of emergency Sunday ahead of what some forecasters have said has the potential to be one of the worst storms in Gulf Coast history.

Snow and ice had been forecast to fall across the I-10 corridor into Lake City and Jacksonville, with perhaps a few ice pellets as far south as Ocala. All precipitation was set to end by daybreak. Temperatures were expected to fall below freezing from Citrus County northward.
