John Monteverdi, San Francisco State University meteorology professor emeritus, said the latest models show the whole coast could be affected by the storm.

“Now remember, this is five days in advance. We’re expecting it into the area [between] Monday night to Tuesday, but things can change between now and then, of course,” Monteverdi said.

While meteorologists cannot say for certain when or how hard the storm will hit, they advise residents to take precautions regardless.

“In terms of items to pack in a bag in case you need to evacuate, we do advise things like first aid kits, medicine, food and water, including for your pets. We advise chargers, batteries, a radio, hygiene products and also important documents like insurance, medical information and personal identification,” Hoang said.

In the next few days, the National Weather Service will provide continuous updates about possible impacts and what parts of the Bay could be most affected.
