Tropical Cyclone Bansi Maintaining Intensity Northeast of Mauritius

At 11:00 p.m. EST on Wednesday the center of Tropical Cyclone Bansi was located at latitude 17.6°S and longitude 60.3°E which put it about 270 miles northeast of Port Louis, Mauritius.  Bansi was moving toward the east-southeast at 8 m.p.h.  The maximum sustained wind was 105 m.p.h. and it was estimated there were wind gusts to 125 m.p.h.  The minimum surface pressure was estimated to be 954 mb.

An eyewall replacement cycle altered the structure of Tropical Cyclone Bansi.  It previously had a small eye which had a diameter of 10-15 miles.  The outer eyewall has not contracted significantly since the inner eye dissipated.  Thus, Bansi is now a tropical cyclone with a large circular eye with a diameter of about 60 miles.  The circulation around Bansi seems to have achieved a rough equilibrium  with its surrounding environment and the intensity did not change much on Wednesday.  Bansi remains over warm Sea Surface Temperatures and in an area of light upper level winds.  So, it is still possible that some intensification could occur in the short term.  When Bansi moves to a higher latitude it will encounter cooler water and more wind shear and start to weaken.

A subtropical ridge near Bansi is expected to start to exert a greater influence and start to accelerate it toward the southeast at a faster speed in about 24 hours.
