The tail end of a frontal boundary is stationary and extends into
the Caribbean from 20N75W across western Jamaica to 18N78W to
northeastern Costa Rica 10N83W. This fronts is underneath a mid-
level diffluent flow that is supporting scattered showers within
150 n mi east of the boundary. A combination of the front and a
trough over the tropical east Pacific is producing scattered
showers and thunderstorms south of 12N and west of 75W. Latest
scatterometer data show fresh to strong winds in the northwest
Caribbean behind the front. The frontal boundary is expected to
dissipate by Saturday morning. Strong trade winds will increase
to gale force near the coast of Colombia in about 48 hours.
