Storms formed during May and September MAY indicate the weak or lesser strength in monsoonal wind ... http://ow.ly/1O0Tm
Path of MAY month Cyclones
If the cyclone tracks of the Month of May is viewed most of them will take re curvature and hit Bangladesh or Myanmar. "Alia" was not an exception. Similarly to day [20 May 2010 / 2135 hrs IST] also it is to think that "LAILA' will follow the suite even after the land fall.
However LAILA has grown through out its journey up to 13-14 km height and slopped SW wards. Most of the rain bands formed NW-SE direction and gave copious rain fall in that route.
Usually when a cyclone eye tends to cross the coast [in the first half portion of a circle / or elongated circle]the winds at northern most crossing point will be North Easterly. Further to its SOUTH,the winds will be NORTHERLY. Still further to south,winds will be North Westerly and WESTERLY respectively. When the center of eye crosses it would be a calm wind. Later,when the other half portion of the circle crosses,winds will be South Easterly at the northern most point, further to its South positions Winds will be Southerly to South Westerly respectively.
Usually Bay storms in May has varied effects on monsoons. There were instances where monsoon was bountiful and there were examples where monsoon was normal or worst.
Storms formed during May and September MAY indicate the weak or lesser strength in monsoonal wind. [Need NOT be the entire monsoon.]

All about weather prediction
The history of weather prediction by man might have started from his cave days. All animals and birds have a built in instinct to keenly observe, analyse and react to the incoming changes. Sunrise and sun set & the eclipse induced darkness are typical examples we see daily[recently saw!]-how all the birds react and the same can be extrapolated to incoming thunder,lightning, showers, winds of various velocities, earthquakes & even tsunamis. But as we hear, read, or observe these fro m our animal/bird kingdoms, we are a bit mesmerized. Only our modernisation and the resulting aloofness from nature, has dwindled or even decimated our 'inborn' faculties.
Though we can claim a lot -computer making, instrument design fabrication, precision modeling etc.- our absolute success in weather predictions is yet to be realized. Even if to be realized, it will be far off! The rates of changes of layers of atmospheric 'ingradients'-concentrations of moisture, dust particles, their physical nature, chemical constitution, etc. as well as specific gravities from time to time are difficult to prdict, even with the best of instruments, supported by the fastest computers. Thus, by the time the "prediction printout" is read by us, the positions of the Sun, Earth, & its atmospheric parameters would have changed, and a different 'weather' sets up to disprove our predictions
Some f the recent studies have shown these points beyond doubts: Our weathermen's rain predictions every season, recent tsunami warnings- occurrences, the manner in which the low pressure areas remain dynamic or static - all have had more than "statistical errors" leading to horrors in daily life!
It was reported some time ago that, the eagles will lay eggs & hatch them if and only if the ‘kids’ are going to face sumptuous food supply for at least three years from the period they plan the ‘failure free family! So they at least three to four years to the future [OVERALL]weather. So we can learn a lot from them about future famine or food supply , rather than sitting in AC rooms operating Computers, Instruments, etc. & ending up in emberassing situations like our Minister Pachuri !
