Catastrophic flooding leaves Puerto Rico without power
Nearly all of Puerto Rico remains without power on Monday after Hurricane Fiona delivered catastrophic flooding that triggered mudslides. Even after the storm made landfall in the Dominican Republic on Monday, the storm system continued to pound Puerto Rico with unrelenting rains as residents were urged to move to higher ground “immediately,” USA Today reported.
The continued catastrophic flooding and heavy rainfall are preventing electrical workers from responding to the blackout.
Alaska experiences its most powerful storm in years
The remnants of Typhoon Merbok brought the most powerful storm Alaska has experienced in years across more than 1,000 miles of the state’s coastline. The storm covered an area as large as the Rockies to the Midwest. The storm caused massive flooding, heavy damage, and power outages, the Weather Channel reported.
The storm also delivered some of the highest water levels recorded in decades, with the tide over ten feet higher than normal. Some homes were knocked off their foundation by the force of the water. Wind gusts were recorded near 70 mph.
A look ahead: More flooding and severe weather midweek
The Storm Prediction Center (SPC) is currently predicting severe weather for the Northeast on Wednesday that could affect parts of Indiana, Ohio, Pennsylvania, and New York, as well as parts of Canada over Toronto and eastward.
In the West on Wednesday, heavy rain could bring flash flooding to parts of Utah, Colorado, Arizona, and New Mexico.
Fall will arrive on Thursday, September 22, but on Wednesday, cooler temperatures could bring mixed precipitation over parts of California, Oregon, Idaho, Montana, Wyoming, and Utah.
