Split string with one or more white spaces

Hello,

I need split a string by one or more white spaces. For example: 

"John Nov11 Boston

Smith        Dec12 NewYork

Linda Oct10  London

Fran   Jan20          Paris"

I need get all the name, date, city. Each field is seperated by one or more white spaces. How can I get those fields with powershell script?  Thanks!
