Unknown
While hurricanes Igor, Julia, and Karl were active elsewhere in the Atlantic on September 17, the precursor to Lisa was first mentioned on the Tropical Weather Outlook issued by the National Hurricane Center (NHC) after having left the African coast only a day earlier. This precursor was an area of low pressure situated along a tropical wave, which developed over a period of a few days into Tropical Depression Fourteen as it travelled west past Cape Verde. [1] The depression strengthened into Tropical Storm Lisa on September 21 when it attained winds strong enough to qualify as such.
Lisa drifted slowly due to weak steering currents caused by the lack of a strong subtropical ridge over the Atlantic, through conditions that, according to the NHC, were favorable for further organization. [2] Although, Lisa did not continue to strengthen, instead, dry air interfered with the developing system and convective activity became limited. By September 22, the storm was downgraded to a tropical depression. This period of weakening did not last long though, after travelling east as a tropical depression, Lisa strengthened into a tropical storm again. Lisa encountered favorable conditions as it turned northwest, and later north. The system began to rapidly intensify, and Lisa became a category one hurricane in just 21 hours. [3] At this time, an eye became visible on infrared satellite imagery. At 0000 UTC on September 25, Hurricane Lisa reached peak intensity northwest of the Cape Verde Islands.
After reaching peak, Lisa continued tracking north over cooler waters and strong westerly upper-level winds, which in turn caused the storm to weaken reapidly. Within 36 hours, not much longer than the system had become a hurricane from a tropical depression, Lisa had done the opposite. Not long after, Lisa became a remnant low as thunderstorm activity significantly subsided. This remnant low continued on a northwesterly track, before slowing down as it turned north where it dissipated approximately 515 nautical miles south-southwest of the Azores Islands on September 19.
