Tropical Daily Planner – Atlantic

Hurricane Ophelia has officially made an extra-tropical transition over the far North Atlantic, therefore, Active Storm Advisories have been ceased. The powerful post-tropical cyclone will impact the British Isles over the next couple of days. Hurricane force winds will be possible over coastal area of Ireland.

The only feature across the Atlantic is now Invest 92L, which is characterized as a low pressure system located over the Greater Antilles. Environmental conditions have become more favorable for development over the past several hours as wind shear slightly decreases across the region and associated convection has become better organized. Tropical development would need to occur within the next day or two before a mid-latitude trough moving into the Western Atlantic turns 92L into an extra-tropical system. Model guidance indicates the chances are decreasing of tropical development to occur.

Otherwise, a large frontal boundary will stall out over the Western Atlantic over the next several days, and model guidance indicates low pressure while likely form along the boundary later this week. This low will likely have frontal characteristic and fail t become a fully tropical system. WeatherOps will monitor for the potential of sub-tropical development.
