this motion is expected to continue this morning. A north-
northwestward motion at a faster forward speed is forecast to begin
later today and continue through late Friday. On the forecast
track, the center of the depression should move across northeastern
Nicaragua and eastern Honduras later today and then over the
northwestern Caribbean Sea Thursday night and Friday. The center is
expected to approach the coast of the Yucatan peninsula late Friday.
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
The depression is forecast to strengthen to a tropical storm before
it moves inland over northeastern Nicaragua. Additional
strengthening is likely over the northwestern Caribbean Sea Thursday
night and Friday.
The estimated minimum central pressure is 1004 mb (29.65 inches).

Honduras...2 to 5 inches, isolated 8 inches
Heavy rainfall will occur over a wide area, including locations well
