IMD 升格"低壓",編號BOB 03。
THE WELL MARKED LOW PRESSURE AREA OVER NORTHWEST BAY OF BENGAL &
NEIGHBOURHOOD CONCENTRATED INTO A DEPRESSION OVER NORTHWEST & ADJOINING
NORTHEAST BAY OF BENGAL. IT LAY CENTRED AT 1200 UTC OF TODAY, THE 11TH JUNE, 2017
NEAR LATITUDE 20.5º N AND LONGITUDE 89.5 ºE, ABOUT 180 KM SOUTH-SOUTHWEST OF
KHEPUPARA (41984) AND 210 KMS SOUTH-SOUTHEAST OF CANNING(42812). THE SYSTEM IS
VERY LIKELY TO MOVE NEARLY NORTHWARDS, INTENSIFY FURTHER INTO A DEEP
DEPRESSION AND CROSS BANGLADESH & ADJOINING WEST BENGAL COAST CLOSE TO THE
WEST OF KHEPUPARA AROUND NOON OF 12TH JUNE, 2017.
ACCORDING TO SATELLITE IMAGERY, INTENSITY IS CI 1.5. THE CONVECTION HAS
ORGANISED DURING PAST 12 HRS AND SHOWS SHEAR PATTERN. MAXIMUM CONVECTION
LIES OVER SOUTHWEST SECTOR OF THE DEPRESSION. ASSOCIATED BROKEN LOW AND
MEDIUM CLOUDS WITH EMBEDDED INTENSE TO VERY INTENSE CONVECTION LIES OVER
NORTH AND ADJOINING WESTCENTRAL BAY OF BENGAL, COASTAL ODISHA AND COASTAL
AREAS OF WEST BENGAL AND BANGLADESH.
AVAILABLE SHIP AND BUOY DATA AROUND THE SYSTEM CENTRE SUGGESTS THE
CENTRAL PRESSURE TO BE ABOUT 990 HPA AND MAXIMUM SUSTAINED SURFACE WIND
SPEED TO BE ABOUT 25 KNOTS GUSTING TO 35 KNOTS. STATE OF SEA IS ROUGH TO VERY
ROUGH AROUND SYSTEM CENTRE.

IMD 昨天升格"深低壓",不過中心登陸孟加拉無緣命名。
The deep depression over southeast Bangladesh & neighbourhood moved northwards with a speed of about 25 kmph in past six hours and lay centered at 1730 hours IST of today, 12th June 2017 over east Bangladesh & neighbourhood near latitude 24.0oN and longitude 91.0oE, about 30 km west-northwest of Agartala and 130 km southwest of Sylhet (Bangladesh). The system is very likely to move north- northeastwards, weaken into a depression during next 12 hours and further into a well marked low pressure area in subsequent 12 hours.

這隻最低氣壓曾只有988hpa,
再次反映北印度洋普遍環流大,
氣壓低且多陸上生物的特性。
