(CNN) — Severe storms with tornadoes and damaging winds will move across the southern United States from eastern Texas and eastern Oklahoma to Alabama this Monday and Tuesday.
Some of these tornadoes may be strong, on the EF2 (strong) scale or higher. The Enhanced Fujita Scale or simply EF is used in the United States to classify the force of a tornado according to the damage they cause. According to the Storm Prediction Center of NOAA’s National Office of Oceanic and Atmospheric Administration, the scale based on the strength of tornadoes ranges from EF-0 to EF-5.
A winter storm over the north-central plains will pull moisture from the Gulf of Mexico north to south, where temperatures are 6 degrees Celsius above normal for this time of year. This will create the right conditions for the development of severe storms.
More than 30 million people are at risk of severe storms this Monday through Tuesday morning in eastern Texas east to western Tennessee and north to Missouri.
Officials have issued a 3 out of 5 forecast for eastern Texas, eastern Oklahoma, northwestern Louisiana, most of Arkansas, and a small portion of eastern Tennessee, and thus eastern Missouri, parts of Memphis, Shreveport, Little Rock, and Tyler, Texas. Tornado Risk Level Released. are included in this area.
Tornadoes and scattered damaging winds from these storms will be the primary threats. Some tornadoes can be intense: damage level EF2 or higher.
These are expected to begin this Monday afternoon, although severe potential remains somewhat uncertain during this round of storms. A second line of thunderstorms is expected to develop Monday night and has the greatest potential to produce tornadoes and damaging winds.
The storm will move east through Tuesday, threatening more than 25 million people from Louisiana east to Georgia and north to Kentucky. A risk level of 3 out of 5 has been issued for eastern Louisiana, southern Mississippi, and parts of southern and central Alabama, including Baton Rouge and Montgomery. Damaging winds seem the most likely threat and tornadoes (some strong ones) are not out of the question.
Heavy rain accompanied by heavy storms will bring the risk of flooding. Flood advisories are posted for approximately 5 million people from eastern Texas northeast to far western Kentucky.
Widespread rain is expected to bring 2 to 3 inches of water, much of which will fall in a short period of time. This will lead to possible flash floods.
