Weather analysis today revealed that there are no areas of concern in terms of tropical development across the Atlantic, Caribbean and the Gulf. Extremely strong wind shear values can be found across the entire Gulf, Caribbean and Atlantic. These very strong wind shear values are highly unfavorable for any sort of tropical development.
Weather analysis also revealed that an upper level low pressure system located to the northwest of Puerto Rico is producing some squally weather across Puerto Rico, the Virgin Islands and the northern Leeward Islands. This squally weather is expected to continue throughout the rest of this weekend into Monday across the Leeward Islands and the Virgin Islands. The squally weather should diminish by about Tuesday.
Western Caribbean Tropical Development Is A Possibility Between June 6 & June 16: The next 2 to 3 weeks or so looks quiet in terms of tropical development chances as the overall environment looks unfavorable for tropical development.
Beyond this, it continues to look possible that an upward motion pulse of the Madden Julian Oscillation will push through the Caribbean and the Atlantic during the period from June 6 to June 16. This upward motion pulse of the Madden Julian Oscillation will inject moisture and energy into the atmosphere across the Caribbean and the Atlantic leading to a favorable background state fro tropical development.
At this point, none of the extremely long range model guidance show any sort of tropical development during that time period. That said, I do think that the prospects for tropical development is something that does need to be watched between June 6 and June 16. The area that I think needs to be watched most closely is the area from the western Caribbean to about the southern Gulf.
While this is something that might need to be watched closely once we get into early June, it’s nothing to be overly worried or concerned about.
The next tropical weather discussion will be issued on Wednesday.
