NHC Tracks Dolly's Remnants and New System Invest 97-L
Listen to the story
The National Hurricane Center (NHC) is monitoring two separate weather features in the Atlantic basin: the fading remnants of Tropical Storm Dolly and a developing disturbance designated Invest 97-L.
In its latest update, the NHC indicated that the chances of Dolly's leftover moisture redeveloping into a organized tropical system have decreased.
Meanwhile, forecasters reported that the likelihood of Invest 97-L strengthening into a tropical depression or storm has risen.
An invest is a designation used by meteorologists to track an area of disturbed weather that shows some potential for tropical development, allowing forecasters to run computer models and issue early guidance before a system is officially named.
Even as Dolly weakens, its remnant moisture is still expected to move across parts of the region, potentially bringing rainfall that could serve as drought relief for areas experiencing dry conditions.
A prolonged drought can strain water supplies, damage crops, and increase wildfire risk, so any meaningful rainfall is often welcomed by affected communities.
Local coverage, including a morning forecast segment for Houston, suggests that residents in the broader Gulf Coast region are paying close attention to how these systems might affect regional weather patterns in the coming days.
The NHC has not specified a firm timeline for when Invest 97-L might organize further, and forecasters caution that tropical development can be unpredictable, with systems sometimes strengthening or weakening rapidly depending on atmospheric conditions such as wind shear and sea surface temperatures.
This period falls within the Atlantic hurricane season, when warm ocean waters and favorable atmospheric patterns make tropical storm formation more common.
The NHC typically issues advisories at regular intervals, updating the public on the probability of development for any tracked disturbance over both 48-hour and seven-day periods.
As of the latest report, no additional details were provided regarding a possible path or intensity for Invest 97-L, and residents in coastal areas are advised to continue monitoring official updates as the situation evolves.
