98P is up. —The preceding unsigned comment was added by 24.83.98.3 (talk • contribs).

Shear is actually somewhat low in this area. If anything develops this early in their season, this might be it. Definitely looks like something's trying to get going down there. --Core des at talk. ^_^ 23:23, 2 August 2006 (UTC)[reply]

Yes it does. bob rulz 04:25, 3 August 2006 (UTC)[reply]

SST in the area is about 28C. 02F is embedded in an easterly trough and is currently being propagated westwards. Deep convection persists around the centre and at this stage there is a strong likelihood of multiple low level centres. 02F is located under the 250 hPa subtropical ridge in an area of strong diffluence. Environmental shear is minimal. Global models have picked up the system and steer it westwards but show reluctance in developing it.
