As Andrea continues to race northward, heavy rainfall will cause urban flooding and travel delays for portions of Atlantic Canada.
Since making landfall Thursday evening over the Big Bend of Florida as a tropical storm, Andrea has continued to produce widespread rainfall totals near 4 inches (100 mm) as it races northward along the Carolinas.
Even as it loses tropical characteristics, Andrea will create widespread rainfall totals between 2 and 4 inches (75-100 mm) as it reaches New England Friday night.
Andrea will bring a soaking rainfall to much of New Brunswick, Prince Edward Island and Nova Scotia on Saturday before speeding across Newfoundland Saturday night. Widespread rainfall totals of 1 to 2 inches (25-50 mm) are anticipated and, because the storm is moving so quickly, much of this rain will fall over only a six- to eight-hour period.
Heavy rain over a short period of time can lead to a high potential of flash flooding, particularly in urban and poor drainage areas. Flooding rainfall will also lead to travel problems, including road closures.
Andrea will also continue to create gusty winds as it heads into the northern Atlantic. According to AccuWeather.com meteorologist Eric Leister, sustained winds between 20-30 mph (30-50 kph) with occasional gusts as high as 50 mph (80 kph) are possible, especially east of the storm center. This places the greatest threat for gusty winds along south- and east-facing coasts.
The storm will exit into the open waters of the northern Atlantic by Sunday morning, giving way to high pressure and sunshine for the end of the weekend and the start of next week.
