Less than a week after Hurricane Laura slammed the Louisiana coast, two new tropical cyclones could develop in the Atlantic basin this week.

SONAR Critical Events: Monday, Aug. 31, 2020, 8 a.m. EDT; Potential areas of tropical development

The first area of interest is off the U.S. Southeastern coast. This tropical wave, about 150 miles southeast of Wilmington, North Carolina, is producing only minimal showers and thunderstorms along the coast and at sea but could organize a little more over the next two days. The National Hurricane Center (NHC) gives it a 70% chance of becoming a tropical depression. Fortunately, this system should remain far enough offshore that it won’t cause major problems. However, it will continue to produce periods of rain and possibly high surf from the South Carolina coast to the Outer Banks of North Carolina. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the system Monday afternoon if necessary.

Another broad area of low pressure associated with a tropical wave is located over the central Caribbean Sea. It has changed little since Sunday. However, the NHC expects environmental conditions to gradually become more conducive for development, and a tropical depression is likely to form during the next couple of days while the system moves west. Interests in Jamaica, Honduras, Belize, Guatemala and the Yucatán Peninsula should monitor the progress of this disturbance.

SONAR Critical Events and satellite: Monday, Aug. 31, 2020, 8 a.m. EDT; Typhoon Maysak

On the other side of the world, Typhoon Maysak will likely make landfall in South Korea by midweek. As of 8 a.m. EDT Monday, it was producing sustained winds of 115 mph, heading toward the East China Sea

Other weather conditions this week

Drivers will run into periods of heavy rainfall and potential flash flooding this week in the Plains and the Mississippi Valley. Rainfall totals of 5 to 7 inches could hit areas from Wichita Falls, Texas, to Oklahoma City; Fort Smith and Little Rock, Arkansas; southeastern Kansas; as well as southern Missouri. Occasional ramp and road closures are possible.

Thunderstorms could produce severe winds, large hail and isolated tornadoes Monday from central and northern Texas to portions of Kansas, Arkansas and Missouri.

SONAR Critical Events and radar: Monday, Aug. 31, 2020, 8 a.m. EDT; Severe thunderstorm risk area

Oppressive heat will spread from southern and eastern Texas into Louisiana, southeastern Arkansas and western Mississippi. Highs will be well into the 90s, with heat index readings of 105 to nearly 115 degrees.
