1. A broad area of low pressure located about midway between Bermuda and the Bahamas continues to produce a limited amount of shower and thunderstorm activity. Environmental conditions are forecast to become slightly more conducive for development during the next day or so while the system moves west-northwestward to northwestward. By Tuesday night and Wednesday, upper-level winds are expected to increase, limiting the chances for additional development, while the system moves northward near the southeastern United States coast.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
2. A non-tropical low pressure system is expected to form north of Subtropical Storm Leslie along a cold front over the central Atlantic by Wednesday. Leslie and the non-tropical low are expected to merge over the central Atlantic, where conditions appear conducive for the low to acquire tropical or subtropical characteristics by the end of the week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
