As the Lorraine tropical storm continued to move southward in the southeastern Indian Ocean, NASA's "Aqua" went overhead and provided predictors overlooking the storm.
At 3:55 am EDT (0755 UTC) on April 26, the moderate resolution of the image spectrometric meters or the MODIS instrument on the Aqua boat captured a visible image of Lorna. Lorna does not look symmetrical and the strongest thunderstorms appear over the west side of the storm. The Joint Typhoon Warning Center or JTWC meteorologists also noted: "Animated enlarged infrared satellite images reflect the central dense cloud function that blurs the circulation center at a low level."
By 11 AM EDT (1500 UTC) on April 26, the Lorna tropical storm had maximum sustained winds near 60 knots (46 mph / 74 km / h). Lorna was centered near 13.0 degrees south latitude and 88.6 degrees eastern length, about 495 nautical miles west of the island of Cocos. Lorna was heading east-southeast.
It is envisaged that Lorna will strengthen for hurricane, strengthening and moving in the south direction. Over the weekend on 27 and 28 April, Lorna is expected to begin the transition to an extra-tropical cyclone.
This means that a tropical cyclone has lost its "tropical" characteristics. The National Hurricane Center defines "extra-tropical" as a transition which involves moving the poles (meaning moving towards the north or south pole) of the cyclone and converting the primary energy source of the cyclone from releasing latent heat to condensation to baroccins ( temperature contrast between hot and cold air masses) processes. It is important to note that cyclones can become extratropic and retain the winds of a hurricane or a tropical storm.
