Hurricane Beryl Explosively Intensified - What’s Next?

 

Just astounding. I try to avoid becoming overly dramatic when discussing weather occurrences, therefore I only use those two terms infrequently. I do appear to be utilizing them more frequently, though. It's the same this morning. I spend my morning ritual combing through the data and models in anticipation of significant weather events. What I am seeing with regard to Hurricane Beryl, a Category 3 storm, is remarkable. By next weekend, it will still be a possible threat to the United States due to its tremendous intensification. What you should know is as follows.

When I want to learn the most recent information about storms, I always start with a reliable source. In its morning talk, the National Hurricane Center states that "Beryl's structure is quickly evolving this morning as it undergoes rapid intensification." The hurricane is approaching an area with low wind shear and extremely warm sea surface temperatures (29 degrees Celsius). The NHC continues, "The most recent NHC intensity forecast will continue to explicitly show rapid intensification over the next day, making Beryl an extremely dangerous Category 4 hurricane before it moves across the Windward islands. There's no obvious reason it shouldn't become a very powerful hurricane before impacting the Windward Islands."

According to the NOAA Glossary, "an increase in the maximum sustained winds of a tropical cyclone of at least 30 kt in a 24-hour period" is considered rapid intensification. It is approximately 35 mph. The explosive nature of Beryl's intensification is demonstrated in Sam Lillo's essay on X, a weather expert and senior software engineer for DTN. Beryl intensified by 65 kt in 36 hours, according to Lillo. He continues, saying that on June 30, it took #Beryl 42 hours to transform from a tropical depression to a powerful hurricane. Six other times in the history of Atlantic hurricanes, this has been done. And September 1st, September, was the earliest day this was accomplished before.

In some respects, the storm is likewise unprecedented. According to Phil Klotzbach, a hurricane expert from Colorado State University, Beryl is the first significant storm of June (Category 3 or higher) to make landfall east of the Lesser Antilles. It will be the earliest Category 4 storm ever recorded if the storm reaches its predicted Category 4 power by July 1. "Hurricane Dennis on July 8, 2005, holds the current Atlantic record for the earliest Category 4 hurricane," wrote Klotzbach. By the way, according to Klotzbach, Beryl is also the third earliest Category 3 storm on record, following Audrey (1957) and Alma (1966).

As Beryl goes deeper into the Caribbean Sea, it is expected to see a little bit more wind shear, which may temper the explosive intensification trend. Forecast models do, however, indicate that shear will decrease once more as the storm approaches the western Caribbean. Recall that decreased wind shear—that is, changes in wind speed or direction as altitude increases—and a high ocean heat content are favorable conditions for storm development. There is an abundance of that for the latter. Additionally, the NHC notes that "an extensive mid-level ridge north of Beryl is expected to steer the system westward or west-northwestward for several days, with no significant track changes from the previous advisory." There is still strong agreement across model recommendations over the expected track.

The track forecast always becomes more uncertain after five days. The European model currently points to a stronger storm that will enter Mexico by the weekend and move south. A weaker storm that enters the Gulf of Mexico and makes landfall in Texas is hinted at by the American GFS models. In the hours to days ahead, as the intensity scenarios in the western Caribbean become clearer, I fully anticipate that the models will agree better. Pay attention if you reside in the United States, Mexico, or Central America along the western Gulf Coast.

Additionally, Beryl is being followed by another storm, but I'll address that later.
