It will be "fair in general and hot during daytime" across the UAE on Tuesday, the National Centre of Meteorology said. Temperatures are forecast to reach 45°C in Abu Dhabi and 43°C in Dubai, with humidity up to 90 per cent in both. The humidity will last until night and into Wednesday morning when there will be a chance of fog over some coastal and internal areas. Light to moderate winds will freshen at times during the day, causing blowing dust. Conditions will be slight in the Arabian Gulf and Oman Sea.
