A tropical storm is forecast to form in the Central Valley Thursday as a tropical depression moves westward toward California, and as the storm moves through the Bay Area, it could cause significant damage, the National Weather Service said.
A storm system is typically characterized by powerful winds, high pressure, and/or heavy rainfall, according to the National Hurricane Center.
The NHC says Cindy is expected to become a tropical storm with sustained winds of 80 mph to 120 mph with gusts up to 150 mph.
It could reach the coast by Thursday evening.
Irma is forecast in the central and southern California from the southern tip of the peninsula to the coast, but Cindy could affect parts of the Central and Northern Sierra Nevada, as well as parts of southern Oregon and Washington state, according the National Interagency Fire Center.
Cindy is moving slowly and could move farther north by Thursday night, according a model that forecasters used.
In its Friday afternoon update, the NHC said Cindy was expected to make landfall early Thursday near Lake Tahoe and become a major hurricane.
That storm will bring “widespread damage to California,” according to an update.
Cindys potential impact on California depends on how fast the storm turns, the hurricane center said.
