"A Polish firefighters rescue team is setting off to Kreuzau in Germany," Morawiecki wrote in a tweet in English on Monday.
He added that Poland "offered 70 desiccant devices which will help our neighbours deal with the consequences of the tragic floods in North Rhine-Westphalia."
Last week, Morawiecki voiced solidarity with Germany and pledged support for people hit by heavy rains, extreme weather and flooding in that country.
According to the Reuters news agency, Germany was hit by the most devastating floods in 60 years, with at least 180 lives lost.
Reuters reported that July's floods were set to be Germany's costliest ever, with the German Insurance Association estimating claims alone at up to EUR 5 billion.
More than 37,000 German buildings have been affected by flooding since the start of July, according to data cited by Reuters.
