SYNOPSIS: A LOW PRESSURE SYSTEM IS EXPECTED TO DEVELOP OVER THE EAST
COAST OF THE UNITED STATES AND TRACK NORTH-NORTHEASTWARD ACROSS NEW
BRUNSWICK ON FRIDAY. RAIN WILL SPREAD ACROSS NEW BRUNSWICK ON FRIDAY WITH
GENERAL ACCUMULATIONS OF 30 TO 50 MM EXCEPT POSSIBLY UP TO 60
MM OVER THE LOWER SAINT JOHN RIVER BASIN.
THERE IS STILL SOME UNCERTAINTY WITH RESPECT TO THE IMPACT THAT HURRICANE
MELISSA, WHICH IS EXPECTED TO TRACK WELL SOUTH OF THE MARITIMES, WILL HAVE ON
THIS SYSTEM. ANY INTERACTION WITH THE TROPICAL MOISTURE FROM HURRICANE MELISSA
COULD CAUSE LOCALLY HIGHER RAINFALL AMOUNTS.

INTO NEW BRUNSWICK FOR SUNDAY AND MONDAY.
