After hanging around the Carolina coast for several days, the year’s second named storm is finally moving on. Tropical depression Bonnie is far enough off the North Carolina coast to finally have taken the rain with it. This trend will continue and eventually, the system will become absorbed within a larger weather pattern and that will be that – no more issues from Bonnie.
In the east Pacific, invest area 91-E is struggling a bit as of late with limited convection associated with it. As such, the NHC has lowered the chance for further development to 60% over the next five days. The system remains well to the southwest of Mexico and there are no indications that it will be turning back towards land even if it does manage to develop.
Now we turn our attention to the Gulf of Mexico where it is possible that we will have to deal with a broad low pressure area that is forecast to take shape over the coming days.
Computer models are in generally good agreement that energy arriving from the Caribbean Sea will gradually consolidate around the Yucatan peninsula this weekend, eventually making its way in to the southern Gulf of Mexico where it could become a tropical storm.
Before folks get too worried about this, let me say that this is not something that appears to be a big wind and surge issue, if it forms at all. What does concern me is the chance for heavy rain for parts of the Florida peninsula next week. As we have seen in Texas with the continued bombardment of rain there, freshwater flooding is a big deal, even coming from so-called “weak” or “lopsided” tropical storms. Even though nothing like that has affected Texas so far this year, rain is rain and the resulting flooding can be devastating and dangerous.
Taking a look at the latest GFS computer model, we can clearly see the overall disorganized look to this potential system at around the 96 hour mark. The low pressure center hangs back over the Gulf while most of the rain and any wind would be located on the east side. This is very typical of June tropical storms due to the fact that upper level winds are still strong across the region, pushing the system faster than it can line up vertically and become better organized, such as what we would see in a hurricane. In this case, even though water temperatures are warm enough for a hurricane, the pattern does not look anywhere near conducive enough for that to take place.
Right now, the NHC is giving the future disturbance a 50% chance of developing. We’ll see if this goes up over the coming days, which I suspect it might. However, what could end up happening is that we just see a broad, strung out low pressure area develop, almost like a frontal wave instead of a true tropical storm, and head towards Florida with plenty of rain.
Elsewhere in the tropics, nothing of concern brewing and I don’t see that changing anytime soon. I’ll have an in-depth look at everything I mentioned in this post during my daily video discussion which will be posted later this afternoon.
