2011 was the busiest year for tornadoes in the U.S. since recording began in 1950, when 1,894 tornadoes were reported, according to NOAA's Storm Prediction Center (SPC).

Driving the news: It's been a busy tornado season so far in 2019. In terms of the most tornadoes in a single period of time, 2019 has ranked 4th in both the 8-to-14-day and 28-to-30 day categories, per NOAA data.

  • As of May 29, there were 549 tornadoes reported in the past 30 days. The SPC had a preliminary count of 935 tornadoes this year as of May 27, though many of these reports were likely duplicates — sightings of the same tornado.
    • 422 tornadoes were reported in March and April, which is well above the 272 three-year average and 273 20-year average, per weather.com.
  • 2019 also has the longest streak of days with 8+ tornadoes and days with 16+ tornadoes.

The busiest years, per data from the SPC:

  1. 2011: 1,894 tornadoes
  2. 2004: 1,820 tornadoes
  3. 2008: 1,685 tornadoes
  4. 2010: 1,543 tornadoes
  5. 2017: 1,522 tornadoes
  6. 1998: 1,440 tornadoes
  7. 2003: 1,374 tornadoes
  8. 1999: 1,364 tornadoes
  9. 1992: 1,312 tornadoes
  10. 2009: 1,305 tornadoes

Maximum pressure campaign escalates with Fakhrizadeh killing

The assassination of Mohsen Fakhrizadeh, the architect of Iran’s military nuclear program, is a new height in the maximum pressure campaign led by the Trump administration and the Netanyahu government against Iran.

Why it matters: It exceeds the capture of the Iranian nuclear archives by the Mossad, and the sabotage in the advanced centrifuge facility in Natanz.

Scoop: Biden weighs retired General Lloyd Austin for Pentagon chief

Joe Biden is considering retired four-star General Lloyd Austin as his nominee for defense secretary, adding him to a shortlist that includes Jeh Johnson, Tammy Duckworth and Michele Flournoy, two sources with direct knowledge of the decision-making tell Axios.

Why it matters: A nominee for Pentagon chief was noticeably absent when the president-elect rolled out his national security team Tuesday. Flournoy had been widely seen as the likely pick, but Axios is told other factors — race, experience, Biden's comfort level — have come into play.
