SYNOPSIS

Isolated thundershowers are forecast across the Cayman area today and into the early evening, supported by an upper-level trough over the Yucatán Peninsula. Moderate winds and slight seas are expected over the next 24 hours, due to a weak pressure gradient across the northwest Caribbean. Radar imagery shows isolated showers in and around the Cayman area moving towards the northwest.
