Andrea is expected drench the northeastern United States Friday night into Saturday and then bring a burst of heavy rainfall to Atlantic Canada Saturday before moving over the open Atlantic Ocean.
The fast movement of Andrea will continue through the weekend, allowing it to reach Ireland and the United Kingdom by Tuesday.
The storm will be extra-tropical by that point after traveling over the cool Atlantic waters, but there will still be a threat for outbreaks of rain and strong winds.
The storm will arrive Monday night into Tuesday with the strongest winds and heaviest rainfall expected across Ireland. Lighter rainfall will spread into Northern Ireland and Scotland during this time with some strong winds, especially near the coastline.
Rains will spread across Scotland, Wales and England Tuesday night into Wednesday along with some locally strong winds.
Rainfall amounts of 12-25 mm (0.50-1.00 inch) are expected across Ireland, Northern Ireland and Scotland with lesser amounts farther east.
Winds of 25-50 kph (15-30 mph) will be common across all of the United Kingdom and Ireland, but damaging wind gusts in excess of 80 kph (50 mph) will be possible from Ireland into Scotland, with the greatest threat along and near southern- and western-facing coastal areas.
