As Andrea races northeastward, heavy rainfall capable of causing urban flooding and travel delays will keep soaking Atlantic Canada through tonight.
The center of Andrea, now a tropical rainstorm, will continue to parallel the northern New England coast through the midday hours of today, reaching Nova Scotia later this afternoon.
The drenching rain accompanying Andrea, however, has already spread to the Canadian Maritimes of New Brunswick, Nova Scotia and Prince Edward Island.
The soaking across these provinces will persist through today before shifting to southern Newfoundland tonight.
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 45 mph (75 kph) are possible, especially east of the storm center. The places with the greatest threat for gusty winds is along south- and east-facing coasts.
The storm will exit into the open waters of the northern Atlantic by Sunday morning, before delivering some rain to the United Kingdom at midweek.
