A rapidly intensifying low-pressure system is developing along the US East Coast tonight with an explosively deepening central pressure from mid 990s into mid 960s over the next 18 hours. The system will generate violent hurricane-force winds around the core and major waves. Fortunately, the majority of it will stay off the US coast. However, the system will pass with its center very near to the Newfoundland tomorrow night, likely producing an intense blizzard over the island. Violent winds and heavy snowfall are expected.
