WATCH: Raging Flood Waters in the Streets of Portugal

The same storm another round of flooding to Morocco has brought flooding issues to Portugal, setting its sights on more of southern Europe this weekend.

Into Friday and Saturday, periods of heavy rain continue to pound on southern Portugal and Spain.

Several places in Portugal, including the city of Lisbon, were seeing flooding as early as Wednesday.

Post by Jakir Bin Shohid. Meteorologist Tyler Roys expects the storm to bring 12 to 40 mm (0.50 to 1.5 inches) with locally 75 mm (3 inches) or more.

The greatest opportunity for the amounts of or in excess of 50 mm (2 inches) will be late Thursday night and Friday when the heaviest rain is forecast to move through. That is when the flood danger will be highest. With the ground already saturated, any torrential rain would quickly trigger new flooding problems. Periods of rain and potentially more flooding issues will follow for Saturday.

The impending rounds of rain could cause low-lying and poor drainage areas to flood quickly, forcing residents to evacuate.

Streams and normally dry riverbeds may also turn into swollen rivers. Remember never to cross such waterways; doing so could have deadly consequences.

Saturday and Sunday, the wet weather likely will shift eastward, into southern France and Italy. Much of this rain, after the flooding issues seen early in the month, will be unwelcome for these areas.
