Houston is seeing a record-breaking number of tornado warnings each day, based on records since 1996 from the Iowa Environmental Mesonet database. The warnings have broken the previous day’s number since the storm hit land on Friday. Meteorologist Daryl Herzmann says the number of warnings given by the National Weather Service are the most noted in any reliable record for the Houston area to date. “The simple explanation is the exceptional nature of what Harvey is doing now,” Herzmann, who oversees the IEM database, told HuffPost. “It has a near perfect environment for tornadoes to form in the southeast quadrant of the storm.”Harvey has precisely the type of chaos that allows tornadoes to thrive: an unstable environment with warm and moist air from the Gulf combined with turning winds, Herzmann said.
