Gaines County

22 W Seminole to 03 1554CST

10 W Seminole 1700CST

Thunderstorms developed over Lea County,

New Mexico during Saturday afternoon on

April 3rd. The most notable of these

thunderstorms was a supercell thunderstorm

that developed near Eunice, NM at 336 PM

CST and moved northeast into Gaines

County. This storm moved very slowly

northeast across the western portions of

Gaines County. Due to the storm’s very

slow propagation, large hail and heavy

rainfall lingered over U.S Highway 62/180

from 3:54 pm to 5 pm CST. This resulted in

up to 1 1/2 feet of hail accumulation and

the closing of U.S. Highway 62/180.

A high precipitation supercell formed in

extreme southwestern Pecos County early in

the morning on Sunday, April 4th, and

moved to the northeast, eventually

affecting Fort Stockton. This thunderstorm

produced extremely heavy rainfall, very

high wind gusts (80 mph estimated), hail

up to the size of golfballs, and flooding

as it moved across the city of Fort

Stockton. Quarter to golfball size hail

was reported by the public. The hail

lasted for ten minutes and accumulated to

Belding Farms complex southwest of Fort

Stockton reported extensive damage

totaling approximately $2.5 million to

pecan orchards.

county. The Old Alpine Highway (U.S.

Highway 67) was closed between Fort

Stockton and Belding. Additionally, U.S.

Highway 285 between Fort Stockton and

Sanderson was closed. During the event, a

sheriff deputy’s vehicle and a truck

stalled in high water. This resulted in

two high water rescues. In addition,

several homes were flooded on the

southeast side of Fort Stockton, and resi-

dents were relocated to temporary

shelters. The hardest hit areas in the

city were the neighborhoods around James

Rooney Memorial Park. Comanche Creek,

which runs through the park, ran well out

3.5 ENE Toyah 04 1630CST

1900CST

A bridge along Interstate 20 just cast-

northeast of Toyah over the normally dry

Salt Draw failed Sunday evening. This

failure was the result of fast-moving

flood waters originating from previous

heavy rainfall over the Davis Mountains.

Hydrologists also credited a residual

flow of water through the draw from the

Toyah dike break early Sunday for contri-

buting to the gradual process that caused

the bridge to collapse. Authorities said

that advance warning of additional runoff

and flooding allowed the interstate to be

closed to both eastbound and westbound

traffic at the first sign of danger to the

bridge. A state official for the Texas

Department of Transportation said that 86

feet of roadway in the eastbound lanes

fell into the river, and that additional

40-foot segments on each side of the

river were also damaged. On the westbound

side, one of the upright supports holding

the bridge had moved six to eight inches,

opening a crack in the roadway.

No fatalities were reported with the

bridge collapse, however, five indirect

fatalities occurred in a multi-vehicle

collision along a detour, U.S. Highway

285, south of Pecos.

cast of the first residence. The tornado

also ripped the tops off of several farm

silos near that residence. Then the

tornado destroyed a barn and a shed about

one mile farther down the road, near

Freedom Drive and Mourning Dove Lane. One

reports indicated several feet of water on

field roads.

Reeves County

3.5 ENE Toyah Flash Flood

A bridge along Interstate 20 just cast-

northeast of Toyah over the normally dry

Salt Draw failed Sunday evening. This

failure was the result of fast-moving

flood waters originating from previous

heavy rainfall over the Davis Mountains.

Hydrologists also credited a residual

flow of water through the draw from the

Toyah dike break early Sunday for contri-

buting to the gradual process that caused

the bridge to collapse. Authorities said

that advance warning of additional runoff

and flooding allowed the interstate to be

closed to both eastbound and westbound

traffic at the first sign of danger to the

bridge. A state official for the Texas

Department of Transportation said that 86

feet of roadway in the eastbound lanes

fell into the river, and that additional

40-foot segments on each side of the

river were also damaged. On the westbound

side, one of the upright supports holding

the bridge had moved six to eight inches,

opening a crack in the roadway.

No fatalities were reported with the

bridge collapse, however, five indirect

fatalities occurred in a multi-vehicle

collision along a detour, U.S. Highway

285, south of Pecos.
