Sunday Morning Update
Bertha has changed little in intensity overnight. The top winds are still officially 50 mph. Currently it is centered 1650 miles southeast of Bermuda, 1450 miles east of San Juan, and 1900 miles east-southeast of Nassau.
Deep convection is bursting again, especially on the western and northern part of the circulation. Some cloud tops have cooled to -60 C

This may translate to some strengthening. Many times it is hard for a tropical cyclone in the formation stages to strengthen when it is moving over 20 mph + like Bertha is.
Bertha will also have a chance for strengthening not only as it slows down, but also as it moves over warmer water. Right now it is over 26 C water, a little cool.
Forecast models mostly recurve Bertha toward Bermuda in several days. A few of the models nearly stall Bertha several hundred miles east of the Bahamas before resuming the northwest track. Since the forecast models usually can't pick the details that well that far ahead in a situation like this, it would be foolish to make a call to say recurving toward Bermuda for sure.
The "other" Bertha, in 1996 has drawn many comparisons. That Bertha formed at around 9 N. This Bertha formed considerably farther north. It would be an incredible feat for this Bertha to reach the U.S. east coast starting at such a high latitude. The odds are well against it.
