A Pineapple Express is a type of atmospheric river where moisture accumulates in the tropical Pacific around Hawaii, bringing heavy rain or snow to the U.S. and Canada’s West Coasts, the National Ocean Service says.

Rain is expected to start on Friday afternoon across New Jersey. After the rain ends Sunday, strong winds gusting up to 40 mph are possible.

Even where there is no risk of snow, heavy rain is forecast for many areas of the UK. Combined with snow melt due to rising temperatures, there is now a risk of localised flooding.

Rain is expected to move into North Jersey this afternoon, bringing steady precipitation and wet roadways through the evening.

A Flood Watch and severe weather alert are in effect for Atlanta and north Georgia today as a cold front brings heavy rain and plunging temperatures.

A moisture plume from near Hawaii is set to bring heavy rain, flooding and avalanche risks to British Columbia, Washington and southeastern Alaska, raising concerns after recent flooding events and excessive snowfall.

Chief Meteorologist Dave Nussbaum says on Friday and Friday night, a slow-moving cold front brings two rounds of heavy rain and storms. Rain totals of 2–4+ inches could lead to flash flooding, especially in flood-prone areas.
