TROPICAL DEPRESSION IDA DISCUSSION NUMBER  29
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL102015
1100 AM AST FRI SEP 25 2015

The cloud pattern is similar to 24 hours ago, and still consists of
a tight swirl of low clouds with a curved convective band to the
east of the center. The overall circulation, however, appears to be
decaying. The initial intensity has been lowered to 25 kt, and given
the strong shear and dry air affecting the cyclone, weakening is
forecast. The depression is expected to degenerate into a remnant
low in about 36 hours or sooner.

The swirl defining the center has been moving northward at about 4
kt. A high pressure system is forecast to develop over the North
Atlantic, and this high will force the shallow depression, or its
remnants, to move toward the northwest during the next day or two.
A sharp turn to the west or southwest is expected on Sunday, and
by then the cyclone could have opened into a trough.
