The method is probably to bring isolated heavy rains with probabilities of seawater inundation in low-lying coastal places.
The National Multi Hazard Early Warning Center of Oman’s Public Authority for Civil Aviation (PACA) issued an alert on the storm on Monday afternoon stating that Hikaa is situated more than central Arabian Sea at longitude 64.1°E and latitude 20.3°N.
The estimated surface wind speed about the centre is in between 34 and 40 knots (60 to 75 km/hr).
The storm was about 430km away from Masirah Island on Monday at 7pm. The closest convective clouds band related with the method was about 320km from Masirah Island.
‘The direct effect of the storm is expected to reach the governorates of South Sharqiyah and Al Wusta by Tuesday, September 24 evening, associated with isolated heavy rains ranging between 30 and 60mm and fresh winds ranging between 25 and 35 knots.’
Numerical climate predictions indicate feasible, gradual weakening of the storm whilst approaching the coastal places of the sultanate,’ PACA stated.
The authority added that rough sea state is anticipated more than the coastal places of South Sharqiyah and Al Wusta with maximum wave height in between three and 6m with probabilities of seawater inundation more than low-level coastal places.
‘The sea state will be moderate over the rest of the coastal areas with maximum wave height ranging between 1.5 and 2.5m.’
The Public Authority for Civil Aviation advised public to take precaution and remain away from low-lying places and stay away from crossing wadis whilst raining.
It also advised fishermen and sea goers to stay away from venturing into the sea and stick to the most recent and updated bulletins from its centre.
