Fernand exiting, 99L dissipating, and the Atlantic quieting down

In brief: The Atlantic tropics are going to trend quieter, with Fernand heading out to sea and Invest 99L finally reaching the end of the road. Behind those? Not much. A significant typhoon hit Vietnam today. Flooding risks will continue in Oklahoma and Arkansas this week.

Tropics

We don’t have a heck of a lot to discuss today in the Atlantic! Tropical Storm Fernand continues to slowly work out to sea and away from Bermuda.

Fernand has strengthened a little since our post yesterday, as expected. However, it’s not exactly healthy. The center seems somewhat displaced to the north side of the thunderstorms, and it’s pretty evident that wind shear is beginning to really hamper Fernand.

Meanwhile, to the south, Invest 99L has finally met its fate it would seem. Where did all the thunderstorms go?

Thankfully, it just took some time but it got here. Look for the remnants of 99L to spread west across the Caribbean, bringing some scattered heavy rain and storms before eventually being buried in Central America or even South America as a small-scale feature. No development is expected, and this should probably close the book on this version of Invest 99L.

Beyond these areas, we see nothing of note in the Atlantic tropics for the next week, probably longer. A very rare and welcome late August and early September break seems to be in the offing this year. We will absolutely take that.

In the Pacific, Typhoon Kajiki made landfall in north-central Vietnam this morning (U.S. time) as the equivalent of about a category 2 hurricane. Around 600,000 people were ordered to evacuate ahead of this storm.

Arkansas and Oklahoma flooding risks

Rain across the Plains will go on as expected, with heavy rain in parts of Oklahoma in particular.

A second round of heavy rain is likely heading into later week as well. This round will be either Wednesday night, Thursday, and Thursday night.

More rain later this week. (NWS Tulsa)

More details in our post yesterday. We’ll keep it there for now. More on Tuesday!
