 Tropical Depression Nineteen-E Discussion Number   1
 NWS National Hurricane Center Miami FL       EP192018
 Issued by the NWS Weather Prediction Center College Park MD
 900 AM MDT Wed Sep 19 2018
 
 Satellite images show that an area of low pressure has developed
 over the Gulf of California overnight within an inverted trough.
 This is also supported by 24-hour pressure falls of 3.7 mb at Loreto
 just west of its center at 1300 UTC. Microwave imagery shows
 curved convective banding features to the east and north of the
 center, suggesting organized convection. Therefore the system
 is being declared a tropical depression with 25-kt maximum sustained
 winds. Infrared imagery shows minimal vertical wind shear over the
 system, with a slight restriction to the outflow on its western
 side, which is confirmed by recent SHIPS output.  However, the
 system has only 12 hours or less over water, and it is expected to
 move inland without significant strengthening.
 
 An upper-level trough moving into the western United States is
 expected to steer the depression north or north-northeast across the
 Gulf of California into northwest Mexico tonight, which is well
 advertised by the track guidance.  The depression is expected to
 dissipate in the 24-36 hour time frame due to steep terrain.
 
 The main impact with the system is expected to be heavy rainfall,
 with 5-10 inch areal average amounts and local amounts to 15 inches
 leading to life-threatening flash flooding and landslides near the
 track of the depression.
