The stationery movement of clouds may perphaps be due to the presence of HIGH pressure ridge hovering over NW & adjoining central India at 850 hPa level. Further the 300 hPa & above level winds are strong SWly and trying to drag it away from East Coast. Today [10.12.2009/0300 UTC] surface charts depicts two or thre isobars closer by, thus indicating more Pressure Gradient Force (PGF)acros isobars. Obviously surface wind force will be stronger in the coast and (land too) and tides will be higher than normal during this period.
