Josephine, Karina Form as Latest in String of Tropical Storms

Two new tropical storms have formed to make a total of four named storms currently at large. Josephine and Karina have added their names to the growing list of this season's tropical storms.

The National Hurricane Center announced Josephine, the 10th named storm of the Atlantic hurricane season, Tuesday. Karina was announced shortly after, forming off Mexico's Pacific coast near the Baja peninsula.

Neither storm is hurricane strength. Josephine has top sustained winds near 40 mph and is moving west at 15 mph. It could be near hurricane strength on Wednesday or Thursday.

Karina has winds of around 40 mph and is expected to remain about at that strength as it moves west-northwest, out to sea. It is expected to weaken to a depression later in the week.
