The weather centre reported heavy rain in Sharjah, Fujairah and Al Ain between 2am and 4am.
It said there was further rainfall in Sharjah and Ras Al Khaimah shortly after 6am.
Videos from Storm Centre UAE showed roads badly flooded after torrential rain.
Residents caught up in wet weather
Emirati fisherman Ahmad Darweesh, from Kalba, said older roads in the area were worst hit by the weather.
“Several roads and mainly old ones have been flooded but the municipality is on site and I saw them dealing with the issue suing pumps to reduce the amount of water,” he said.
“One of the roads I passed by near the Clock Tower was flooded from pavement to pavements.
“The rain is very heavy. It started yesterday and would stop for only five or ten minutes then resume.”
Khalid Saleem, who lives in Khor Fakkan, said water flooded the street and the pavement before it made its way inside the fitness centre he works at.
"Some machines were also flooded by water not just the floor."
He said most shops on the same street are facing the same problem which regularly happens during spells of heavy rain.
It was a similarly soggy story in Fujairah.
Khalid Salim from the Merbah area of the emirate, said some poorly-maintained roads quickly flooded.
“They are full of cracks and holes that are now flooded by rain water,” he said.
“It was very heavy around dawn but is now moderate, it didn’t stop though.”
Fatima Al Shujaa, head of media department at Dibba Fujairah Municipality, said no flooding of homes had been reported but the authority remained on alert.
Police in Fujairah called on drivers to stay away from flooded areas and to keep a safe distance from other vehicles during the rainy weather.
Unstable weather in the UAE and Oman is expected to continue for the next few days, with haze and rain expected in some areas.
Forecasters at the NCM said it will be cloudy over scattered areas of the Emirates on Wednesday.
The centre said wet weather was in prospect because of the formation of convective clouds until 9pm on Wednesday.
The temperature is likely to fall slightly too, with lows of 29°C in Dubai and 30°C in Abu Dhabi, but the weather is expected to clear up by Saturday.
Thursday looks to be similar, with fresh winds and possible rain likely to continue. However, the NCM predicted a slight increase in temperature, with lows of 30°C in Dubai and 31°C in Abu Dhabi.
On Tuesday, the weather forecaster issued an alert over dusty conditions as rain fell across the country.
