Powershell:Get list of first level folder in a document library

How can i get only list of 1st level folders in a documnet library in sharepoint  to generate report. 

$list.Folders is getting me all sub folders also.

 #Folder Name in each of the folder
foreach ($folder in $list.Folders) 
{
   $FileNames=""
   $foldFirstLvl = $list.ParentWeb.GetFolder($web.Url + "/" + $list.RootFolder.Url + "/" + $folder.Name)
   $filesCount = $foldFirstLvl.Files.Count
   
   #File Counts from each SP folder
   Add-Content .\$LogFileName -Value ([string]::Concat($folder.Name))
   
   
}
