Item 5.  Other Events

Southwest Gas Corporation (Southwest) expects its second quarter 1999 operating
results to be better than analysts' estimates. Analysts' estimates range from a
loss of $0.40 to a loss of $0.35 per share. Southwest anticipates its net loss
will be approximately one-third of the consensus street estimate. Southwest
attributes the improvement to colder-than-normal weather as its service
territories experienced 37 percent more heating degree days than normal during
April and May.
