Disturbance likely to develop below Cayman Islands

From Mike’s Weather Page

Our western Caribbean spot is highlighted by the NHC this AM at 20%.

Shear expected to relax as it heads generally northward.

Conditions could be favorable for development with high ocean heat content (warm deep water), positive MJO (promotion of thunderstorms), and low SAL (lack of dry air).

Will watch close.
