Cyclone LEHAR - 10:30pm, Where is it ?

Where is Cyclone LEHAR ? ... It has undergone rapid weakening during past 6hrs after 5pm ... http://ow.ly/i/3R5Dc 

At present, it's a cyclone with winds reaching to 60 to 80 kmph.
Going by the present weakening trend, it may be "shot down over sea itself".
The system will downgrade to Deep depression during next 6hrs and reach Machilipatnam and Ongole coast around morning.
Heavy rain is still expected along central,S-central,N Andhra coast during next 24hrs.
Showers may even reach upto Odisha coast tomorrow.
By evening of 28-Nov-2013, the entire system may fizzle out along Machilipatnam coast itself, similar to Cyclone Helen.

This rapid weakening is caused by DRY winds from N,N-W India, latest analysis show that the Cyclone is encircled by these dry winds. This parameter is coupled with "Not so favorable Sea surface temperature along coast" as well.

LEHAR - drifting into Machilipatnam's RADAR range

LEHAR now pushing into RADAR range of Machilipatnam... here's the RADAR image as of 6:30pm.
Showers nearing central, N Andhra coast.
The system continues to drift W-N-W, as of 5:30pm it is positioned here 14.30 N , 84.55 E.

Here's the satellite visible shot at 4:30pm shows Heavy convective activity seen over W,N-W quadrants and recent (6pm) cloud top temperatures reveal -42.6 C, this is sign of less convective activity, weakening.

As Cyclone LEHAR is moving W-N-W, threat to #Chennai is now 90% out of Question.
For #Chennai - Due to LEHAR, moderate or light rain possible after midnight and before tomorrow evening.

Satellite visible at 9:30am shows the BIG cloud mass of LEHAR.

Position is plotted here... 13.43N,86.37E (9 am)

Now almost ALL weather models agree to a central, S-central Andhra coast... very near to Ongole with present intensity or as slightly weakened Cyclone on mid-morning of 28-Nov-2013.

Now, the outer bands are reaching S,central Andhra coast, #Chennai and N Tamilnadu coast.
Rain expected to start along S,central Andhra coast from late evening today.

At present the Cyclone is interacting with DRY winds from N,N-W India.
During next 24hrs, it'll move into slightly colder waters. 
The system may not further intensify during the next 24hrs.

Present location is plotted here ... it has reached Central Bay parallel to #Chennai.

Latest track forecast by various weather models suggest a central Andhra coast by morning / noon of Thursday, 28-Nov-2013.

There are 2 anti-cyclones which is and "may" guide the system in next 24 to 36hrs.
A low, mid level anti-cyclone is expected to drift into N-E Bay from Myanmar.
The present upper level anti-cyclone over N-E Andhra and along S-E coast is expected to move N-E in 24hrs, these 2 systems will make sure the Cyclone moves in a W-N-W direction till tomorrow evening.

Sub Tropical Ridge Western End shows a slight shifting towards the Indian Coast ( i.e.Shifting West). This would enable Lehar to maintain a NW track for the next 24/36 hrs.

The Very Severe Cyclone has maintained its strength at T4.0 since 07 PM IST till 17.30 pm IST..and winds estimated at 65 knts. Pressure estimate 985 mbar.

Currently the core centre, located at 12.9N and 89E, is moving along the Southern Periphery of the Ridge. 
A Sat Image showing the central core and upper winds has been shown here to gauge the Ridge as well as the fluctuating central core.

Lehar will now encounter drier air as it tracks towards the NW. The drier air is encircling the cyclone from the North-West and SW.
