NOAA's Climate Prediction Center is forecasting a 40% chance for a near-normal Atlantic hurricane season — June 1 to November 30, 2019 — determining a 70% likelihood of 9-15 named storms, of which 4-8 could become hurricanes.

The backdrop: This year's outlook comes after 2018's devastating season, with Cat. 5 Hurricane Michael hitting the Florida Panhandle. The average hurricane season produces 12 named storms, of which 6 progress to hurricanes status and 3 turn into major hurricanes.

Details: The 2019 outlook reflects climate factors including El Niño — anticipated to continue and El Niño tends to increase wind shear over the tropical Atlantic, which can inhibit tropical storm and hurricane formation. Offsetting El Niño is a combination of warmer-than-average sea-surface temperatures in the tropical Atlantic Ocean and Caribbean Sea, and a heightened west African monsoon, increasing the potential for hurricane activity.

NOAA also issued seasonal hurricane outlooks for the eastern and central Pacific basins.

  • A 70% chance of an above-normal season is predicted for both the eastern and central Pacific regions.
  • The eastern Pacific outlook calls for a 70% probability of 15-22 named storms, of which 8 to 13 are expected to become hurricanes.
  • The central Pacific outlook calls for a 70% probability of 5-8 tropical cyclones, including tropical depressions, tropical storms and hurricanes.

Driving the news: This season marks the addition of NOAA’s Earth-observing satellites, expected to enhance the hurricane forecast models used by forecasters to help users make critical decisions in real time.

Major climate news arrived on Tuesday when Chinese President Xi Jinping said China would aim for "carbon neutrality" by 2060 and a CO2 emissions peak before 2030.

Why it matters: China is by far the world's largest greenhouse gas emitter. So its success or failure at reining in planet-warming gases affects everyone's future.
