TROPICAL DEPRESSION IDA DISCUSSION NUMBER  30
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL102015
500 PM AST FRI SEP 25 2015

Not much has changed today and resilient Ida is still there. It
consists of a tight swirl of low clouds with a curved convective
band to the east of the center.  The initial intensity is estimated
at 25 kt. The overall circulation is expected to decay as the
depression continues to move within an environment of high shear and
dry air. The depression is expected to degenerate into a remnant low
in about 24 hours or sooner.

The center has been moving toward the northwest at about 5 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, and then, as the high to the north
intensifies, a sharp turn to the west or southwest should occur
Sunday night or Monday.
