Winter Storm in Upper St. Martin, Louisiana

Temperatures fell below freezing during the late evening of the 14th as showers developed across the parish. Rain changed over to freezing rain then quickly over to sleet. Sleet changed over to light snow by the end of the event. Around half an inch of sleet and snow accumulated. All roads were icy making travel difficult. The I-10 Atchafalaya Bridge closed and remain closed for multiple days.

The first in a series of Arctic Cold Fronts arrived during the 12th pushing tide levels down along the coast, however the subfreezing temperatures and winter weather did not arrive until the 14th. The event on the 14th began at many places as a light glaze of freezing rain, but quickly changed over to sleet or snow. Another round of winter weather occurred on the 17th, however this round was mainly freezing rain. The long duration event set many records in the area and rivaled the historic freezes of the region. The event was likely the longest and coldest since December 1989.
