1. An elongated area of low pressure located more than 150 miles off
the coast of South Carolina is producing disorganized showers and
thunderstorms well to the east of the center of circulation. Strong
upper-level winds should prevent any significant tropical or
subtropical development during the next day or two. By Sunday,
however, environmental conditions could briefly become marginally
conducive for some subtropical development of the low. By early
next week, the low is expected to interact with a frontal boundary,
which should end the opportunity for any subtropical or tropical
formation. Regardless of development, the low is forecast to meander
just offshore the Carolinas for the next few days, occasionally
bringing locally heavy rains and gusty winds to eastern portions of
the Carolinas through the weekend.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
