The 17th named storm of the season developed in the western Caribbean Friday evening, becoming Rafael with winds sustained at 40 mph.
Rafael will continue to churn through the western Caribbean and affect the US and British Virgin Islands today.
The main threats will be gusty winds, soaking downpours and rough seas.
Some of the hardest hit spots will see anywhere from 2-4 inches of rain, with localized locations up to 10 inches possible.
This sort of rain will be capable of causing mudslides, rockslides and flash flooding.
As Rafael heads through the Virgin Islands and dances with the western-half of Puerto Rico, he will head north toward Bermuda by the early to middle part of next week.
More clouds and cooler weather can be expected across the Bay Area through the holiday weekend and into the new week.
Cloudy skies and cooler weather will linger across the Los Angeles area through the holiday weekend and early in the new week.
It might feel more like late October rather than late May in the Northeast on Friday night as temperatures dip well below normal.
Memorial Day marks the unofficial start to summer and summer warmth will dominate the Northeast next week, but that does not mean an end to shots of cooler air.
Showers and thunderstorms threaten to interfere with Memorial Day festivities across roughly two-thirds of the United States.
