Keeping A Close Eye On Central Atlantic Disturbance This Week

The fast-paced 2020 hurricane season rolls on. This week we’ll be keeping a close eye on Invest 92L – likely to become our next named storm – as it nears the Caribbean. The next name on the list? Isaias [ees-ah-EE-ahs].

The bottom line right now is that this is still a few thousand miles away, and we have several days to watch it. In the United States there is no cause for concern yet.

It’s always tough to lend much credence to any model output until a storm actually forms. That being said, at the moment there does seem to be some consensus for a track near, or just north of the northern Caribbean Islands. In that scenario, a northward turn out to sea before reaching the U.S. becomes more likely.

The quicker the system develops in the next few days, the more northern track it’s likely to take. If it takes its sweet time to get organized, it’s likely to take a more southern track through the Caribbean Sea. We’ll check back in a couple days and go from there.

Hanna Now A Hurricane; Texas Landfall Expected Saturday Afternoon

Hanna has taken full advantage of its favorable environment over the last 24 hours, and steady strengthening continues this morning. Hanna is now a hurricane with max sustained winds of 75 mph. The hurricane hunters continue to find falling pressure and an expanding wind field, and deep convection has been wrapping around the center of the storm, closing off the eye wall. Strengthening should continue up to the time of landfall early this afternoon.

The center is currently about 60 miles offshore and landfall looks to take place near, or just south, of Corpus Christi. Hurricane-force winds will be pushing water onshore the next few hours. Storm surge may be as high as 5 feet in spots.

Heavy rainfall will lead to flooding issues across parts of South Texas and northeastern Mexico through the weekend. Isolated rainfall totals of up to 18 inches are possible.
