Further sandstorms are expected to sweep in on Thursday due to strong winds offshore over the Arabian Sea. The National Centre of Meteorology has issued a weather alert warning of gusty to strong winds, with rough to very rough seas off the coast. That will cause sand to blow in, affecting visibility at times. The warning is in force up to 8pm on Thursday. The density of the dust should drop, according to the weather bureau. It will be partly sunny, with temperatures reaching a high of 27°C on the coast and 28°C inland. Humidity will rise overnight to bring a risk of fog and mist over some coastal and internal areas, which will clear to leave a partly sunny day on Friday, with no further sandstorms. There will be gusts of up to 40kmph over the sea, which will be rough at first. Saturday will begin the same, with a chance of more early mist and fog, but there may be an increase in temperatures, reaching 29°C on the coast and 30°C inland. Winds should drop a little. The picture will be similar on Sunday, according to the weather bureau, but sandstorms could return again on Monday.
