NHC : 10%
2. A non-tropical area of low pressure with gale-force winds is located
about 150 miles north of Bermuda and is moving south-southeastward
at about 15 mph. Although there are some signs of organization, dry
air and strong upper-level winds are expected to limit development
of this system over the next couple of days. However, conditions
could become a bit more conducive for this low to gradually acquire
some tropical characteristics early next week as the low moves south
and then drifts westward to the southwest of Bermuda.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

NHC 展望提升至50%,趨向美國東岸。
1. A broad area of low pressure located about 400 miles south-
southeast of Cape Hatteras, North Carolina, continues to produce
disorganized showers and thunderstorms. Environmental conditions are
expected to become slightly more conducive for development, and a
tropical depression could form tonight or Tuesday while the system
moves west-northwestward to northwestward. By Tuesday night and
Wednesday, upper-level winds are expected to increase and limit
the chances for additional development while the system moves
northward near the southeastern United States coast. Regardless of
tropical cyclone formation, this system will likely enhance rainfall
across portions of northeastern South Carolina and eastern North
Carolina Tuesday and Tuesday night. In addition, dangerous surf
conditions and rip currents are expected along portions of the
North Carolina coast on Tuesday. For more information, please see
products from your local National Weather Service office.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
