Search within a character array

I have this character array:

 EAST WINDS 11 TO 16 KNOTS. SEAS 2 TO 4 FEET. SCATTERED                                                                                                                
 SHOWERS. % its indices being row (13), column (1:65) from a text file

I want to create a structured variable taking only phrases of this sentence. For example if I type:

'Today'

The output must be:

 Today = 

    winds: 'EAST WINDS 12 TO 14 KNOT'
    waves: 'SEAS 3 TO 4 FEET'

Here's the catch, I am taking this sentence from a forecasting web page that updates daily, meaning the indices changes daily. One day the wind forecast may be on row 16 and with more or less columns (1:56 for example). The character array MUST be this information especifically, winds and waves and it could have more or less columns. What function or commands can I use?
