Two new weak developments
Wednesday 10th June
Disturbance Six we picked up yesterday developing in the tail of an eastbound frontal system as often occurs at the start and end of the season. This is now 700 miles east of Bermuda aimlessly drifting north over an area of warm water, but with some upper level shear ensuring interruption in the convection column. This may still produce something, but likely to remain fairly weak and won't approach any land mass.
Early signs of the transatlantic production line getting steam up have produced Disturbance Seven around 400 miles north of Guyana, moving west at 13 knots. This is expected to pass over Trinidad and the Windward Islands tomorrow night bringing thunderstorms and some heavy showers in places but conditions aloft are not encouraging for rising air to organise itself into anything substantial.
