Tropical Depression IDA Forecast Discussion Number 30

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.

Tropical Depression IDA Forecast Discussion Number 29
2015-09-25 16:32:16| National Hurricane Center (Atlantic)
Issued at 1100 AM AST FRI SEP 25 2015 000 WTNT45 KNHC 251432 TCDAT5 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.

Tropical Depression IDA Forecast Discussion Number 28
2015-09-25 10:37:11| National Hurricane Center (Atlantic)
Issued at 500 AM AST FRI SEP 25 2015 000 WTNT45 KNHC 250837 TCDAT5 TROPICAL DEPRESSION IDA DISCUSSION NUMBER 28 NWS NATIONAL HURRICANE CENTER MIAMI FL AL102015 500 AM AST FRI SEP 25 2015 A few convective cells have been forming near Ida's center during the past several hours, but most of the thunderstorm activity remains displaced more than 150 n mi to the east-northeast due to 20 kt of shear. Maximum winds remain 30 kt based on the latest Dvorak CI number from TAFB, but it's clear from satellite imagery that the shear and dry air has caused a steady degradation of the cyclone's structure during the past few days. With moderate vertical shear expected to continue and the mid-level relative humidity forecast to drop to between 30 and 40 percent, additional weakening is anticipated during the next couple of days, and Ida could degenerate to a remnant low by 48 hours. The NHC intensity forecast shows the possibility of the maximum winds increasing again by days 3 and 4, but this is the result of a tight pressure gradient between the remnant low and strong high pressure over the north Atlantic--not a restrengthening of Ida's circulation. Based on global model guidance, the remnant low could open up into a trough by day 5, if not sooner. Ida is being steered generally north-northwestward, or 335/3 kt, by a low-level ridge over the eastern Atlantic. The depression should move northwestward through 48 hours and then abruptly turn westward or west-southwestward during its remnant low stage when strong low-level ridging develops over the north Atlantic. The NHC track forecast is close to the various consensus aids and shows a slightly faster motion of the remnant low after 72 hours compared to the previous forecast.

Tropical Depression IDA Forecast Discussion Number 27

Issued at 1100 PM AST THU SEP 24 2015 000 WTNT45 KNHC 250239 TCDAT5 TROPICAL DEPRESSION IDA DISCUSSION NUMBER 27 NWS NATIONAL HURRICANE CENTER MIAMI FL AL102015 1100 PM AST THU SEP 24 2015 The center of Ida, like most of the Atlantic tropical cyclones this year at some point, is exposed to southwest of a bursting area of deep convection. The initial intensity is kept at 30 kt in accordance with the latest TAFB Dvorak classification. A combination of shear and dry air aloft is expected to persist near Ida for the next few days. These conditions are forecast to cause the cyclone to gradually weaken. Although the cyclone could move into a slightly more favorable environment at long range, there isn't likely to be much left of Ida to take advantage of the conditions. The latest NHC forecast is close to the model consensus for the first few days, then is below that aid at days 3 and 4, leaning more heavily on the weaker solutions of the HWRF, GFS and ECMWF models. Both the GFS and the ECMWF now show Ida opening up into a trough by day 5, and the official forecast follows that trend. Ida is moving erratically north-northwestward at about 4 knots. The depression should turn northwestward tomorrow and head in that general direction for a couple of days due to a weak subtropical ridge forming over the central Atlantic. After that time, the cyclone is expected to be a shallow system, and will likely move to the west or west-southwest as it is steered by a strong low-level ridge. The guidance has shifted leftward, which makes sense for a weaker cyclone, and the official NHC prediction follows suit.
