Issued at 500 PM AST FRI SEP 25 2015 000 WTNT45 KNHC 252035 TCDAT5 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.
