EF1 tornado in San Augustine County, Texas

An EF-1 tornado with winds estimated between 95-105 mph touched down along the northern shore of Sam Rayburn Lake in the back of the Anthony Harbor subdivision off of Anthony Drive, snapping and uprooting numerous trees as it moved north northeast through the subdivision to Highway 83. Several trees fell on homes in this subdivision, where the tornado was at its widest and strongest. The tornado then shifted northeast and crossed over the northern tip of the lake north of the Ayish Bayou bridge, where the force of the winds resulted in two electrical transmission lines leaning in a northeasterly direction. The tornado then moved into a heavily wooded area north of Highway 83 near its intersection of County Road 430, where it snapped and uprooted several more trees on Red Oak and Evergreen Drives. The tornado finally lifted as it crossed Farm to Market Road 1751, where a large pine tree was uprooted.

After a brief respite from severe thunderstorms during the predawn hours on April 29th, additional strong to severe thunderstorms developed from the late morning hours through much of the afternoon and evening on April 29th, and lingered through the early morning hours on April 30th. These storms developed along and south of a warm front which lifted into Southeast Oklahoma and the northern sections of Southwest Arkansas, in a warm, moist, and unstable air mass ahead of a series of upper level disturbances that approached the region from the west. Large hail, damaging winds, and isolated tornadoes were the result over East Texas by early afternoon, with these severe thunderstorms spreading east into Northern Louisiana and Southwest Arkansas during the late afternoon through the overnight hours. A total of 10 tornadoes touched down across East Texas and Southwest Arkansas, which included a 27 mile long track tornado which touched down near Lindale, Texas in Smith County and remained on the ground before lifting northwest of the community of Bettie in Upshur County. Widespread flash flooding also developed over extreme Southeast Oklahoma and Southwest Arkansas from late morning through the afternoon on the 29th in response to showers and thunderstorms containing heavy rainfall which moved repeatedly over the same areas. The flash flooding spread across much of East Texas, extreme Northwest Louisiana, and the remainder of Southwest Arkansas during the afternoon through the overnight hours, flooding/washing away numerous roads with water entering homes as well. The severe weather and flash flooding diminished around daybreak on April 30th as the showers and thunderstorms weakened and pushed east of the area.
