Weak Tropical Storm Maria expected to combine with eastern Canadian weather front to produce rain

Tropical storm Maria is weak as it approaches Atlantic Canada, but it is expected to merge with a front over Eastern Canada late in the week, resulting in a heavy rainfall for Nova Scotia and Newfoundland on Sept. 16.
The Canadian Hurricane Centre said the upper winds in the atmosphere have not allowed Maria’s winds to intensify as the storm tracks towards Canada.
But although wind speeds are not increasing, the storm resulted in “a lot of rainfall” over Puerto Rico, the centre noted. As of Sept. 13, the U.S. National Hurricane Center forecast between four and eight inches of rain over Puerto Rico, with 15 to 20 inches of rain over elevated regions of the country.
Computer models are suggesting Maria will merge with a front over eastern Canada later in the week of Sept. 12-16.
“The current forecast challenge is determining how that merger will take place,” the Canadian Hurricane Centre notes. “At the least, we can expect the front to acquire extra moisture from the tropical storm and associated rainfall to affect Nova Scotia and/or Newfoundland on (Sept. 16).”
