The low is expected to acquire some tropical characteristics as upper-level winds become more conducive, and a subtropical or tropical cyclone will likely form during the next few days. The low is forecast to move northward on Wednesday and turn northwestward on Thursday, before heading northeastward out to sea by the end of the week. A NOAA Hurricane Hunter aircraft is scheduled to investigate this system tomorrow afternoon, if necessary. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...high...80 percent $$ Forecaster Stewart
