00:24 Mexico Earthquake Makes Waves in Pool A powerful earthquake in southern Mexico Tuesday turned a swimming pool into a wave pool in Mexico City.

At a Glance Since Harvey dropped 60+ inches of rain, Texas has been abnormally dry.

Parts of eastern Texas are now 8-10 inches behind on rainfall since September.

A more northward storm track has kept rain away from the southern Plains and Gulf Coast.

Parts of southeastern Texas have entered moderate drought just three months following the final landfall and deluge of Harvey along the Texas coast.

Hurricane Harvey dropped more than five feet of rainfall in a few spots of southeast Texas while most of the region saw flooding conditions in the nearly week-long stall of Harvey.

"Since Harvey, we have had 90 days of below normal rainfall and average monthly temperatures have been 5 degrees above normal," according to Nikki Hathaway at NWS Houston . From Sep. 1 through Nov. 30, Houston recorded its fifth driest meteorological fall on record with only 5.15 inches falling during that time, which is about 36 percent of average.

The City of Houston had its fourth driest November on record, according to the Southeast Regional Climate Center . Houston recorded 0.50 inches during the last month of meteorological autumn, a month that typically sees 4.34 inches of rain. The rain observed this November was in the first week of the month, meaning Houston now has a nearly three-week stretch of dry weather going.

Severe to extreme drought has developed this week in parts of Arkansas, Oklahoma, northeastern Texas and northern Louisiana, which did not see much help in the way of rainfall from Harvey, if any.

The dry stretch was created in large part by a far northern storm track that has kept storm systems over the northern tier of the U.S. and into Canada. This stubborn storm track has created an 8+ inch deficit in rainfall over the last 90 days from Missouri to the Gulf Coast (in red on this map ).

Occasional cold fronts have tried to make their way to the Texas coast, but most have arrived with little to no moisture.

Along with the lack of moisture, temperatures were slightly above average during the fall and as much as five degrees above average for the month of November.

"Evaporation rates have been high, not allowing much moisture to be retained within the soil," said Hathaway.

This increase in drought coverage across the South may have assisted a top-10, one-week boost in drought coverage nationally:

Drought is defined as being in the moderate, severe, extreme or exceptional classification scheme provided by the U.S. Drought Monitor.
