Needed Rain Threatens Flooding for Spain, Portugal

A storm system over the Atlantic will push into Portugal and Spain, bringing beneficial rain for most, but also threatening flash flooding through the weekend.

Showers and thunderstorms on Saturday and Sunday will bring an end to a rather dry stretch of days for interior parts of Portugal and western Spain. Even though summer is knows as the drier season in western Europe, cities such as Badajoz, Salamanca and Leon in western Spain have had less precipitation than normal this summer.

"Each day this weekend, thunderstorms could produce 0.25 to 0.75 inches (6-19 mm) of rain" warned Meteorologist Tyler Roys. This would help to alleviate some of the drier conditions.

"However, some places that have a slow moving thunderstorm could see as much as 1.5 to 2.0 inches (38 to 50 mm) through the weekend," Roys noted. This much rain might not be able to be absorbed by the dry ground, leading to the possibility for flash flooding on Sunday. Meteorologist Eric Leister also remarked in his international weather blog that, although this is not a large amount of rain alone, "it could mark the start of rain returning to the region for the fall season."

With the system sliding northward through the weekend, the beneficial showers and thunderstorms will likely not reach Madrid. The Spanish Capital has only seen forty-two percent of their normal rainfall this year, including a completely dry month in August.
