Satellite data gives forecasters a leg up on severe weather. NASA has just released an animation of visible and infrared satellite data showing the development and movement of the Great Plains tornado outbreak, using data from NOAA’s GOES-13 satellite. There were more than 135 reports of tornadoes and 124 different warnings over April 14-15, 2012.
Two NASA satellites have been measuring rainfall and cloud top temperatures in Tropical Storm as it has been “going loopy” in the Mozambique Channel over the last couple of days. Irina is making a cyclonic loop, something that a tropical cyclone does on occasion whenever there are a couple of weather systems that push it in different directions.
On March 5, 2012, Irina’s maximum sustained winds had increased to near 50 knots (57.5 mph/92.6 kph), , up from 40 knots (46 mph/74 kph) over the last several days. Forecasters at the Joint Typhoon Warning Center expect Irina to strengthen more at sea over the next day, and then begin to weaken.
