Tropical Storm BLAS

Tropical Storm Blas Discussion Number  21
NWS National Hurricane Center Miami FL       EP022022
300 AM MDT Sun Jun 19 2022
Blas remains a sheared tropical cyclone, with deep convection 
restricted to the eastern half of the system's circulation. The 
tropical storm is maintaining its limited convection for the moment 
despite having moved over marginally cool sea surface temperatures 
below 26 deg C. The initial intensity of 40 kt is based on an 
average of Dvorak estimates from TAFB and SAB. Blas should slowly 
weaken during the next few days as it continues to move through a 
dry and stable surrounding environment and over marginal SSTs. The 
official forecast shows Blas becoming a remnant low in about 36 h 
and dissipating during the middle of the week. 
Blas is moving slowly toward the west-northwest (295/4 kt). As the
tropical storm weakens, it should be steered westward by
low-level trade wind flow for the next couple of days. Very little
change was made to NHC official track forecast, which is near the
middle of the global deterministic model forecasts.
