Debby will exit the Northeast on Saturday.

Debby made landfall in Florida as a Category 1 hurricane on Monday and crawled up the East Coast all week.
Latest forecast
Debby, now a post-tropical cyclone, is slamming the Northeast with heavy rain.
A life-threatening flash flood emergency was issued in northern Pennsylvania and southern New York due to fast-moving floodwaters.
A flood watch remains in effect for parts of nine states from South Carolina to New Hampshire due to the intense rain.
Showers with some downpours will continue across the Northeast through the evening. Tornadoes are also possible.
Debby will be gone by Saturday morning.
Power returns to some Florida customers as Debby moves northeast
As of Monday evening, 146,034 customers are without power in Florida, according to the latest update from a U.S. power outage map.
This marks an improvement from Monday morning, which saw nearly 300,000 customers without power at 9:50 a.m. ET, the height of outages across the state.
During a press conference in Tallahassee Monday morning, Gov. Ron DeSantis said the state's emergency department had 17,000 linemen working to restore power in the wake of the storm.
"We have a lot of restoration personnel ready to go," DeSantis said.
Debby weakening, but threats of tornadoes, heavy rain continue
Tropical Storm Debby continues to weaken, with maximum sustained winds down to 45 mph as of 8 p.m. ET. The weather pattern is moving very slowly to the northeast at 6 mph, and the center is currently about 50 miles east of Valdosta, Georgia.
Even though Debby is now inland and continues to weaken, many of the impacts -- especially the heavy rainfall and dangerous flash flood threat -- will not abate for several days. For many locations in coastal Georgia and South Carolina, the worst is yet to come.
The tornado threat continues along portions of the Georgia and South Carolina coasts this evening and into tonight. A Tornado Watch remains in effect from Savannah, Georgia, to Charleston, South Carolina, until at least 1 a.m. ET.
Parts of Florida, including Sarasota and Lakewood Ranch, are reporting over a foot of rain from Debby, and portions of Suwannee County, including Live Oak, are getting around a foot as well.
So far, parts of Georgia, including Savannah, are reporting nearly 4" of rain. The same can be said for Hilton Head, South Carolina.
Conditions will continue to deteriorate across much of South Carolina overnight Monday into Tuesday, with widespread areas of heavy rain and the potential for dangerous, significant flash flooding during nighttime hours.
Coastal flooding and storm surges will continue to increase in the coming hours as winds increase and more persistent heavy rain moves in, heading into high tide along the Georgia and South Carolina coasts.
By late Tuesday afternoon or early evening, the center of Debby will likely be moving off the Southeast coast and into the Atlantic, where it will meander for about 24 hours before likely turning back toward the coast and potentially making another landfall as a tropical storm somewhere along the South Carolina coast by Thursday morning or afternoon.

Curfew set for Charleston, South Carolina
A curfew will go into effect overnight for Charleston, South Carolina, due to Debby, city officials said Monday.
Thoroughfares leading into the peninsula will be closed from 11 p.m. ET Monday to noon ET Tuesday, the city said, as the region braces for potential impacts such as tropical storm-force winds, heavy rain and isolated tornadoes.
"We urge everybody to stay inside, stay indoors and do not travel," Charleston Mayor William Cogswell said at a press briefing Monday evening.
