Taiwanese authorities announced that offices and schools would close on Tuesday afternoon in five cities, including Yilan.
Maria was 500 kilometres (310 miles) east of the northeastern coastal town of Yilan with gusts of up to 190 kilometres an hour as of 10 am local time (0200 GMT), the weather bureau said.
Its impact was expected to be the strongest from late Tuesday to early Wednesday, with downpours up to 500 millimetres (19.7 inches) forecast in some areas, the bureau added.

Premier William Lai warned local authorities and the public to "remain vigilant" for the first typhoon of the season in Taiwan.
He urged people to stay indoors and cooperate with the government's disaster prevention plans.
The typhoon will not make a direct hit if it continues on its current trajectory, which would see it skim off northern Taiwan, according to the weather bureau.
Taiwan is frequently hit by typhoons in the summer. Last year more than 100 people were injured when Typhoon Nesat battered the island, causing flooding and widespread power outages.
