Dubai: Residents of Masafi, Diftah in Ras Al Khaimah welcomed a flash rainstorm on Tuesday afternoon, according to the national weather centre on Tuesday.

Meanwhile, spotty intensive rainfall is expected in the eastern and southern parts of the country on Wednesday as cloud cover mounts amid continuing high heat, the weathermen said.

Flash rainstorms are accompanied by increasing humidity, said a forecaster, making the summer weather hot and sticky for those venturing outdoors throughout the day.

Seasonal temperatures are expected to be in the normal range with highs of 49 degrees Celsius inland, in the mid-40s along the coast and up to 39 degrees Celsius in the eastern areas of the Al Hajar mountain range, according to the National Centre of Meteorology and Seismology.

“Hot to very hot weather will continue in general, hazy and partly cloudy at times, the amount of clouds will increase over the eastern and some southern areas by afternoon, with chance of convective clouds, associated with different intensities of rainfall, and may be extended to the internal areas,” said the forecaster.

The combination of heat, haze and humidity will be tempered in some areas by light to moderate winds in general, freshening at times during daytime, causing blowing dust/sand over the exposed areas.

"The relative humidity will increase during night and early morning over the coastal and some internal areas, with a probability of fog formation toward west. Sea will be slight to moderate in the Arabian Gulf and moderate in Oman Sea.”

The longer view of the weather includes continued seasonal summer heat norms, the weather bureau said.

Sporadic rainfall events are also forecast for Thursday and beyond as “convective clouds, associated with different intensities of rainfall, and may be extended to the internal areas.”
