Scattered showers are expected today across the Virgin Islands. Daytime high temperatures will be in the upper 80s to low 90s. The extreme outer bands associated with Hurricane Jerry may affect the local area late tonight into early Saturday and on Sunday as well, bringing some shower activity to the local area.

Hazardous marine conditions will continue through the weekend due to a northerly swell. Seas to ten feet with easterly winds between 5-15 knots (7-17 miles per hour). Small craft advisories are in effect for the Atlantic offshore and coastal waters and passages. In addition, a High Surf Advisory is in effect until Sunday morning for St. Thomas and St. John. There is a moderate or high risk of rip currents for most beaches across the territory.

IN THE TROPICS
Earlier this morning, Hurricane Jerry was located approximately 403 miles east of the Virgin Islands with top winds of 105 miles per hour. The hurricane is moving to the west-northwest at 16 miles per hour.  Hurricane force winds extend 25 miles from the center while tropical storm force winds extend outward up to 80 miles from the center.  On the projected path, the center of Jerry should pass an estimated 167 miles northeast of St. John at 2 a.m. Saturday morning.  At that time, Jerry is forecast to be a Category One hurricane with top winds of  90 miles per hour.  There are no watches or warnings posted for the Virgin Islands. The winds associated with Hurricane Jerry will not affect the Virgin Islands.

In addition, a tropical wave located about 700 miles east of the Windward Islands is producing disorganized showers and thundershowers. The wave is expected to move quickly westward at about 20 miles per hour during the next few days, and some development is possible while it approaches and moves across the Windward Islands this weekend. Upper-level winds appear less conducive for development once the wave moves into the eastern Caribbean Sea early next week.There is a 10% chance of formation over the next two days, and a 30% chance of development through five days.

Also, a tropical wave is forecast to move off the west coast of Africa this weekend. Environmental conditions are expected to be conducive for development, and a tropical depression could form early next week while the wave moves westward across the eastern tropical Atlantic. While there is only a slight potential for development over the next two days, there is a 60% chance of development through five days.
