January 2, 2015 - A flash flood watch in effect for parts of east and northeast Texas, including Shelby County, Carthage, Lufkin Texas, South Central Arkansas, and Northwest and North Central Louisiana to a line southeast of Magnolia, Arkansas to Shreveport, LA.
Showers and thunderstorms will produce heavy rainfall overnight and on Saturday across an area that had received 2 to 3 inches recently. Flash flood watch in effect from 9pm this evening through Saturday afternoon.
From tonight through Saturday afternoon additional rainfall amounts of one to three inches with isolated higher amounts will occur over an area that had received from two to three inches of rain from New Years through early Friday morning. This rain event will be due to a surface low pressure system lifting northeast across the ArkLaTex with a warm front lifting northeast with the low and a cold front trailing southwest from the system as an upper level storm system over Arizona and New Mexico moves northeast out into the plains providing disturbances aloft and added lift and instability. A deep and rich supply of moisture will be available for efficient rain production.
Heavy rainfall over the saturated soils from previous rains will result in rapid water runoff and result in flash flooding and filling of small creeks, streams, rivers, and low water crossing. Do not drive into areas with high or rapid moving water.
A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
