NASA's Aqua satellite spotted Tropical Cyclone 08P as it was developing in the South Pacific Ocean. Tropical Cyclone 08P, or 08P formed east of Extra-tropical cyclone Bart.

Tropical cyclone 08P developed on Feb. 22 at 0300 UTC (Feb. 21 at 10 p.m. EST), and strengthened by 1500 UTC (10 a.m. EST) into a tropical storm with near 35 knots (40 mph/62 kph). 08P is expected to maintain strength over the next day as it moves in a southeasterly direction in the South Pacific's open waters. 08P was located near 25.4 degrees south latitude and 165.8 degrees west longitude, about 660 nautical miles south-southeast of Pago Pago, American Samoa. 08P is moving to the southeast at 33 knots (38 mph/61 kph).

Like its predecessor Bart, Tropical Cyclone 08P is also dealing with vertical despite forming under those conditions.

The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite took a visible image of the storm on Feb. 21 as it was developing. The MODIS image showed wind shear was pushing the clouds and strongest storms southeast of the low-level center of circulation. The MODIS image also showed that 08P is elongated from northwest to southeast.

The Joint Typhoon Warning Center or JTWC noted that dry air associated with a nearby trough (elongated area of low pressure) is wrapping around the northern quadrant of Tropical Cyclone 08P. JTWC expects 08P to become extra-tropical in a day.
