[71] The storm tracked westwards, and intensified further into a Severe Cyclone Storm, early on December 1. [19] As the system moved over land, it weakened gradually into a depression over east Bangladesh & neighbourhood due to land surface interaction and thereafter into a well marked low pressure area. Bangladesh was also affected by severe weather conditions. Stronger-than-usual surface trade winds and unfavorable upper-level winds worked to keep 2017's typhoons weaker than usual, despite the presence of sea surface temperatures (SSTs) that were more than 1°C (1.8°F) warmer than average over much of the Northwest Pacific.
