Re: Invest 90E

The whole area is a mess in the carribean. A upper trough of low pressure that came down a couple days ago pulled up the itcz as a elongated trough from the EPAC to the WCAR.. on the sw side of the trough (in better upper air support from the trough hanging down over central america) a low pressure system formed and is been migrating underneath the trough. The trough though is now weakening and pulling out as a ridge builds in from the eastern carribean. The low pressure system over the EPAC near 10N and 86W will get pulled NNE and into central america. Another weaker low is situated off the east coast of Nicaragua near 12N and 81W. This low dont have the upper level enviroment due to the EPAC low proximaty. With the EPAC low moving inland on Thurs.. the weaker low off Nicaragua should get pulled into Honduars or Belieze by Friday. Now with that said a tropical wave of low pressure may develop near Jamaica as upper level winds calm down as 1 the upper trough is now out of the way and the EPAC low is now a trough over central america. This wave will have a chance to develop and move WNW towards the Yucitan and S Gulf.. There is nothing really to pull anything in the near term north to florida or anywhere in the gulf right now ...and besides anything after 3 days has a growing amount of error.
