JANUARY 20 2010 SEVERE WEATHER |
| Overview |
| A supercell thunderstorm developed near the Lake Charles area before moving northeastward across Jefferson Davis and Allen Parishes. The storm strengthened significantly as it traveled across Evangeline Parish, with a mesocyclone evident on radar imagery. Wind damage from downbursts associated with the forward flank downdraft and rear flank downdraft of the storm occurred near and northeast of Ville Platte. Continuing across northern St. Landry Parish and southern Avoyelles Parish, the storm produced one brief tornado near Morrow that was photographed by a stormchaser. Several reports of large hail were also received around Big Cane. The supercell then moved into southern Mississippi. |
