(Oct. 12, 2018) The National Weather Service has issued high-wind and flash-flood advisories for Nantucket Friday.

The wind advisory is in effect through 5 p.m., with 25 mph winds and gusts to 50 expected. The winds will develop by mid-morning and continue through mid-day before diminishing by early evening. Winds of this speed may knock down some large tree limbs and result in isolated power outages. A few weakened trees may also be knocked down given that they are fully leafed and the ground is saturated. 

The flash-flood watch is in effect through 2 p.m., as heavy rainfall is expected to continue through mid-afternoon. Rainfall of up to six inches is possible on Nantucket, which could lead to localized flash flooding, particularly in poor drainage areas.
