Fire service crews and staff battled to prevent damage to the hospital following heavy rain in the area on Tuesday night, which closed the department from 8pm to 11pm.
The Republic of Ireland's Health Service Executive (HSE) said clinical areas were not affected by the flooding and advised those needing treatment to attend another facility.
In a statement, it said: "After torrential rain in the Letterkenny area there has been some flooding at Letterkenny General Hospital.
"As the car park and roadway are flooded, access to the emergency department is very curtailed.
"There is a low level of flooding due to water leaking into the reception and administrative areas at the department but clinical areas have not been affected."
The statement continued: "Patients already in the emergency department and hospital inpatients have not been affected.
"To expedite the clean-up, the department has gone off call until midnight after which it is expected full services will be restored.
"As the emergency department is inaccessible due to external flooding, patients are being asked to attend their GP or Nowdoc or to go to Sligo Regional Hospital or Altagelvin."
The incident comes almost exactly a year after a huge deluge hit the hospital causing tens of millions of Euro worth of damage.
After last year's flooding €43m was spent on repairs and refurbishment work.
Sinn Féin councillor Gerry McMonagle said he was angry to yet again see the hospital close its emergency department because of flooding.
He said: "It is one unmitigated disaster, not just for the hospital but for the people of Donegal.
"Once again our new accident and emergency has been ruled out due to 15-20 minutes max of rain, this is just not good enough."
The heavy rain has also disrupted parts of Northern Ireland with the Roads Service warning of flooding in parts of Cookstown and Magherafelt.
The Met Office has said heavy and thundery showers can be expected through into Wednesday morning, bringing a risk of localised flooding.
