010900Z POSITION NEAR 16.6N 62.7E. TROPICAL CYCLONE (TC) 03A, LOCATED APPROXIMATELY 560 NM SOUTH- SOUTHWEST OF KARACHI, PAKISTAN, HAS TRACKED NORTH-NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDICATES THAT TC 03A HAS CONTINUED TO DEVELOP WITH IMPROVED CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER (LLCC) AND A 010235Z TRMM MICROWAVE IMAGE DEPICTS A MICROWAVE EYE. WITH IMPROVED CERTAINTY IN POSITION, TC 03A HAS BEEN RELOCATED WESTWARD OF THE PREVIOUS TRACK POSITION. THE INITIAL INTENSITY WAS SLIGHTLY HIGHER THAN A PGTW DVORAK ESTIMATE OF 45 KNOTS AND INDICATES TC 03A HAS INTENSIFIED FASTER THAN PREVIOUSLY ANTICIPATED. UPPER LEVEL DIVERGENCE IS PROVIDING GOOD RADIAL OUTFLOW ALOFT AND VERTICAL WIND SHEAR (VWS) HAS DECREASED TO 10 TO 15 KNOTS. TC 03A CONTINUES TO TRACK NORTH-NORTHWESTWARD ALONG THE WESTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR) AND WILL BEGIN TO TURN NORTHWARD AS IT ROUNDS THE STR AXIS. BY TAU 72, TC 03A SHOULD TURN NORTHEASTWARD AND ACCELERATE AS THE SYSTEM CRESTS THE STR AXIS AND MOVES UNDER THE INFLUENCE OF A DEEPENING MID-LATITUDE SHORTWAVE TROUGH. THE MAJORITY OF THE MODEL GUIDANCE SUPPORTS THIS TRACK WITH THE EXCEPTION OF WBAR, WHICH SHOWS A SLOW WESTWARD TRACK. TC 03A WILL CONTINUE TO INTENSIFY, UNTIL BY TAU 96, WHEN TC 03A IS EXPECTED TO MAKE LANDFALL. THE SYSTEM WILL WEAKEN RAPIDLY AND DISSIPATE OVER LAND BY TAU 120. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 010600Z IS 19 FEET.

ARB 02/2010/05 Dated:01.06 .2010
Time of issue: 1130 hours IST
Sub: Deep depression over eastcentral & adjoining westcentral Arabian Sea -(Precyclone watch for Gujarat coast.
The deep depression over eastcentral & adjoining westcentral Arabian Sea remained practically stationary and lay centred at 0830 hrs IST of today, the 01st June 2010 near latitude 15.5 0N and 63.50E, about 1050 km southwest of Mumbai, 1050 km south-southwest of Naliya (Gujarat) and 1120 km south-southwest of Karachi.
The current environmental condition and Numerical Weather Prediction (NWP) models suggest that the system would intensify into a cyclonic storm and move initially in a north-northwesterly/northerly direction for next 24 hours and then recurve northeastwards towards Gujarat & adjoining Pakistan coast.
Based on latest analysis with NWP models and other conventional techniques, estimated track and intensity of the system are given in the Table below:
Date/Time(IST) | Position (lat. 0N/ long. 0E) | Sustained maximum surface wind speed (kmph) |
01-06-2010/0830 | 15.5/63.5 | 50-60 gusting to 70 |
01-06-2010/1130 | 16.0/63.0 | 55-65 gusting to 75 |
01-06-2010/1730 | 16.5/63.0 | 65-75 gusting to 85 |
01-06-2010/2330 | 17.0/63.0 | 65-75 gusting to 85 |
02-06-2010/0530 | 17.5/63.0 | 75-85 gusting to 95 |
02-06-2010/1730 | 18.5/63.5 | 85-95 gusting to 105 |
03-06-2010/0530 | 20.0/64.0 | 95-105 gusting to 115 |
03-06-2010/1730 | 21.5/65.5 | 105-115 gusting to 125 |
04-06-.2010/0530 | 22.5/67.0 | 115-125 gusting to 135 |
Under the influence of this system, fairly widespread rainfall with isolated heavy to very heavy falls would commence over coastal areas of Gujarat from 3rd June 2010 and increase thereafter. Squally winds with speed reaching 55-65 kmph gusting 75 kmph would commence along and off Gujarat coast from 2nd June 2010 and increase gradually.
Sea condition will be very rough along and off Gujarat coast from 2nd June 2010. Fishermen are advised not venture into the sea.
Next bulletin will be issued at 1430 hrs IST of 01ST June 2010

Pendulum like UFO Light in Chennai Sky
Did any one see a strange light over Chennai’s skies yesterday?
There were reports of strange lights over the skies of Chennai yesterday night. NDTV Hindu had a live call in show yesterday night from around 10pm – 11pm and a lot of callers reported the sightings from many parts of the city. Most people described it as a bright white light which moved like a pendulum and this is the second such sighting in recent time.
NDTV Hindu tried getting our weatherman Mr Ramanan on the show to comment but he said that he cannot commet on the reports as he is on leave, looks like he is on a long leave
Strange lights sighted again over Chennai !!! This time, photos are available!

Update on TS 03A:
The depression over Arabian Sea remained practically stationary, but has intensified into a deep depression and lay centred at 0530 hrs IST of today, the 01st June, 2010, at 15.5°N and 63.5°E about 1050 km southwest of Mumbai. The winds are at 35 Knots and core pressure at 998 Hpa.
This system would intensify rapidly due to the low "aloft" at the rate of 15 Knots /day, into a cyclonic storm and move initially in a northwesterly/ north-northwesterly direction for next 24 hours and then recurve northeastwards towards India/Pakistan border. Re-curving will take effect as fresh western disturbance would affect Northwest India from tomorrow, 2nd. June onwards.
Rainfall effect at present on land is negligible, and will be between 10-20 mms over the Goa and Maharashtra coast from Wednesday, and Gujarat coast and Gujarat interior from Thursday.
Due to the W.D, dust raising winds would intensify over Rajasthan, Delhi and Gujarat during next 2 days.

010300Z POSITION NEAR 15.9N 63.8E. TROPICAL CYCLONE (TC) 03A, LOCATED APPROXIMATELY 570 NM SOUTH- SOUTHWEST OF KARACHI, PAKISTAN, HAS TRACKED NORTH-NORTHWESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY INDICATES THAT TC 03A HAS CONTINUED TO CONSOLIDATE WITH IMPROVED CONVECTIVE BANDING AND CENTRAL CONVECTION DESPITE LIGHT TO MODERATE, EASTERLY VERTICAL WIND SHEAR (VWS). A 312115Z NOAA-18 89 GHZ IMAGE DEPICTS MULTIPLE CONVECTIVE BANDS OVER THE WESTERN SEMI-CIRCLE WITH THE CENTER POSITIONED ON THE NORTHEASTERN EDGE OF A DEEP CONVECTIVE BURST. THERE IS FAIR CONFIDENCE IN THE CURRENT POSITION BASED ON THIS IMAGE. THE CURRENT INTENSITY IS ASSESSED AT 35 KNOTS AND IS BASED ON DVORAK ESTIMATES OF 35 KNOTS FROM KNES AND PGTW. RECENT BUOY OBSERVATIONS NEAR THE CENTER ALSO SUPPORT A STRENGTHENING SYSTEM. A BUOY (23707) 110 NM SOUTH-SOUTHEAST INDICATED SLP NEAR 1002.2 MB AND SST OF 30C AND A BUOY (23708) 110 NM NORTH INDICATED SLP NEAR 1000.0 MB AND SST NEAR 31C. THE LLCC IS LOCATED WITHIN A GENERALLY FAVORABLE ENVIRONMENT UNDER AN UPPER- LEVEL ANTICYCLONE WITH GOOD OUTFLOW ALOFT. AS INDICATED ON THE TOTAL PRECIPITABLE WATER PRODUCT, THE SYSTEM HAS A DEEP MOISTURE ENVELOPE. VWS HAS DECREASED SLIGHTLY OVER THE PAST 12 HOURS AND IS EXPECTED TO DECREASE FURTHER WITHIN THE NEXT 12-24 HOURS. TC 03A IS TRACKING SLOWLY ALONG THE WESTERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE (STR), WHICH IS CENTERED OVER WESTERN, CENTRAL INDIA. THE SYSTEM IS EXPECTED TO TRACK SLOWLY NORTHWARD BUT SHOULD ACCELERATE BY TAU 48 AS THE STR BUILDS. BY TAU 72, TC 03A SHOULD TURN NORTHEASTWARD AND ACCELERATE AS THE SYSTEM CRESTS THE STR AXIS AND MOVES UNDER THE INFLUENCE OF A DEEPENING MIDLATITUDE SHORTWAVE TROUGH. THE MAJORITY OF THE MODEL GUIDANCE SUPPORTS THIS TRACK WITH THE EXCEPTION OF WBAR, WHICH SHOWS A SLOW WESTWARD TRACK. BOTH THE GFS AND GFDN DISPLAY ERRONEOUS TRACKS THROUGH TAU 48 BUT COME INTO BETTER AGREEMENT IN THE EXTENDED TAUS. THE GFS 500 MB HEIGHTS AND VORTICITY INDICATE TWO VORTICITY MAXIMA ROTATING CYCLONICALLY WITHIN AN ELONGATED CIRCULATION. THIS ERROR ACCOUNTS FOR THE ERRONEOUS NORTH-NORTHWESTWARD TRACK THROUGH TAU 48. THE GFDN INDICATES AN UNREALISTIC EASTWARD TRACK INTO THE STEERING RIDGE THROUGH TAU 24. SINCE THESE ERRORS APPEAR TO OFFSET EACH OTHER, THIS FORECAST IS CLOSE TO BUT FASTER THAN THE CONSENSUS. THE ECMWF SOLUTION SUPPORTS THE CURRENT FORECAST AND IS CLOSE TO THE MODEL CONSENSUS. TC 03A IS FORECAST TO INTENSIFY AT A 10-15 KNOT PER DAY RATE BUT WILL WEAKEN RAPIDLY AFTER MAKING LANDFALL NEAR TAU 96 AND WILL DISSIPATE BY TAU 120. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 010000Z IS 17 FEET. NEXT WARNINGS AT 010900Z, 011500Z, 012100Z AND 020300Z

Under the influence of this system, fairly widespread rainfall with isolated heavy to very heavy falls would commence over coastal areas of Gujarat from 3rd June 2010. Squally winds with speed reaching 45-55 kmph would commence along and off Gujarat coast from 2nd June 2010.
