Tornadoes are not common in Central Texas. But on May 5, 1922 – 95 years ago – a pair of tornadoes ripped through Austin, killing 13 and injuring 44.

The Day in WX History Twitter feed sent out striking photos maintained by the Texas Historical Society:

The second photo is the view as seen from a rooftop on downtown Congress Avenue, according to The Portal of Texas History.

The photo is, itself, a trip through Austin history. In it, according to the Portal of Texas history, are:

  • The Queen Theater at 700 Congress Avenue
  • The Walter Tips Building at 708-710-712 Congress Avenue
  • The F. W. Woolworth & Company at 800-802 Congress Avenue.
  • The side of the Paramount Theater is also visible.
  • There is a painted sign, on a building in the foreground, for Maxwell House Coffee.

As a side note: It’s obviously cool we still have the Paramount. But the Queen, Woolworth building and Maxwell House sign have long since disappeared, yet Austin appears to have maintained its cool. Added to it, even.

Though tornadoes are not common in Central Texas, the region might have already endured two rounds of them this year: In the overnight hours of Feb. 19-20, two twisters struck in eastern Williamson County and two cut a path in northern Hays County; on April 2 in western Travis County, eyewitnesses said they saw a waterspout form over Lake Travis just west of Austin.

Another tornado-related anniversary will happen later this month. On May 27, 1997, one of the fiercest tornadoes on record hit the northern Williamson County town of Jarrell, killing 27 people and obliterating the Double Creek Estates subdivision.


How good is the U.S. Drought Monitor’s news for Texas?

Look at those two maps. The first shows a Texas in remarkably good shape going into the hottest part of the year. The second is the best drought news in nearly two decades.

Less than 5 percent of the country is experiencing drought, according to the U.S. Drought Monitor. That is the lowest percentage since the drought monitor began issuing weekly updates, according to an interesting post from the Climate Central web site. (Which also warns this picture could be caused in part by a more extreme wet-dry cycle caused by global climate change.)

In Texas, a wet two-year stretch has erased the epic drought that devastated livestock, sent temperatures soaring and created widespread concern about the state’s water supplies. As of May 2 (the most recent data available) 91.38 percent of the state is drought free. Only 7.18 percent is experiencing unusually dry conditions and 1.44 percent is in moderate drought. None of the state is in severe, extreme or exceptional drought.

In September 2011, 85 percent of Texas was in exceptional drought.

That drought was eventually broken in 2015, which for much of Texas was among the wettest years on record, a period that transformed Central Texas’ main reservoirs, lakes Buchanan and Travis, went from being one-third full to so full the agency that manages them has had to take occasional flood-control measures. Another example of how the rainfall has affected parts of Texas: the lush tree canopy in Austin.

Thanks to some recent rains, only handful of Texans are now living through drought, and even that is of the mildest variety.

A little over a month ago, on March 28, 10.6 million Texans were living in unusually dry areas, 4.5 million were in moderate-drought areas and 43,552 were in severe-drought areas.

But now, only 5.7 million Texans are living in unusually dry areas — and only 214,298 of the state’s nearly 29 million people are living in an area experiencing drought. Even they are all living in areas of moderate drought. No Texans are living in severe, extreme or exceptional drought.

Widespread drought does not appear on the way this summer or fall. Texas is now nearly drought-free despite going through the warmest first four months of year on record. Most forecasts are also calling for a summer with average temperatures — with about 15 to 20 days of 100-degree weather, Lower Colorado River Authority meteorologist Bob Rose expects — along with average rainfall.

Forecasters are also expecting an El Niño weather pattern to form in the Pacific this fall. That typically means cooler-and-wetter-than-normal conditions in Texas.

So enjoy our relatively wet weather. Climate scientists say Texas will be getting hotter over the next 50 years, history shows that widespread drought will hit Texas again someday and worries about water will probably return. But for now, drought is not in the near-term forecast.

How many hurricanes will form this summer? The government has a forecast

The Atlantic hurricane season starts June 1 and you can expect between five to nine hurricanes to form, which is a little above the average according to the National Oceanic and Atmospheric Administration.

Forecasters with NOAA, which just released its official hurricane forecast, “predict a 70 percent likelihood of 11 to 17 named storms (winds of 39 mph or higher), of which 5 to 9 could become hurricanes (winds of 74 mph or higher), including 2 to 4 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher),” according to a statement posted on the NOAA web site.

The forecast includes Tropical Storm Arlene, which formed unusually early in April.

The average hurricane season has 12 named storms, six of which become hurricanes, and three of which become major ones. The 2016 season was the most active since 2012, which had 15 named storms, including 7 hurricanes and 4 major ones.

Hurricanes can devastate the Gulf region, as Katrina, Rita and Ike did in years past, but they tend not to hit Central Texas in the same way. Here, the worry tends to be storms that spin off the periphery of hurricanes. Those storms can, in turn, lead to high winds, tornadoes and heavy rainfall that causes the top weather risk in the region: flooding.

The hurricane forecast calls for a 45 percent chance of an above-normal season, a 35 percent chance of a near-normal season, and only a 20 percent chance of a below-normal season.

“The outlook reflects our expectation of a weak or non-existent El Niño, near- or above-average sea-surface temperatures across the tropical Atlantic Ocean and Caribbean Sea, and average or weaker-than-average vertical wind shear in that same region,” Gerry Bell, lead seasonal hurricane forecaster with NOAA’s Climate Prediction Center, said in the statement.

As to one of the key questions – whether a hurricane will devastate any coastal communities – the forecast is silent. After all, as a wise man once said, predictions are difficult, especially about the future.

 

What’s happening with El Niño? LCRA forecaster has an unexpected answer

El Niño, after looking fairly likely for months to make an appearance this year, will probably not appear in its full majesty after all, according to Lower Colorado River Authority meteorologist Bob Rose.

“Recent observations and forecasts now indicate the develop of El Niño is not nearly as certain as it was just a month ago,” Rose said in a video blog entry. A National Climate Prediction Center update strikes a similar tone, putting the odds of an El Nino forming at less than 50/50.

El Niño is a weather pattern in which warmer than normal ocean surface temperatures in the Pacific tend to bring wetter, cooler and more unsettled weather to Central Texas.

“While sea surface temperatures in the tropical Pacific remain much warmer than normal, there has been no engagement between these warm waters and the atmosphere up above,” Rose said. Therefore, long-range models have backed away from an El Niño forecast.

“The latest outlook for summer and fall calls for a pattern of near to slightly above normal rainfall,” Rose said, adding – and speaking to the fear that lurks in the hearts of all Central Texans – that “summer temperatures look to be moderately hot, but not record-setting.”
