How do I skip a text string within a cell array

I have a text file input that I divided in a {43 x 1} cell array, and the sentences are strings. I would like to skip some information from the text file.

The text file cells are these:

 'REST OF TODAY'
 'TROPICAL STORM CONDITIONS POSSIBLE. EAST NORTHEAST'
 'WINDS 28 TO 33 KNOTS. SEAS 8 TO 12 FEET. INTERMITTENT SHOWERS AND'
 'SCATTERED THUNDERSTORMS. '

and I am proceding the following way:

    row = find(strncmpi(outcell, 'REST', 4));
    str1 = outcell(row(1)+1);
    str2 = outcell(row(1)+2);
    S1 = regexprep(str1{1}, 'TO', ' : ');
    S2 = regexprep(str2{1}, 'TO', ' : ');
    unite = [S1 S2];
    [win, wav] = strtok(unite, '.');
    wavchar=char(wav);
    winchar=char(win);
    REST_OF_TODAY.Winds = winchar;
    REST_OF_TODAY.Waves = strtok(wavchar(3:end), '.');
    REST_OF_TODAY

The output is this:

 REST_OF_TODAY = 

    Winds: 'TROPICAL S : RM CONDITIONS POSSIBLE'
    Waves: 'EAST NORTHEASTWINDS 28  :  33 KNOTS'

and I want it to be like this:

 REST_OF_TODAY = 

    Winds: 'EAST NORTHEASTWINDS 28  :  33 KNOTS'
    Waves: 'SEAS 8 TO 12 FEET'

In other words, skip the sentence 'TROPICAL STORM CONDITIONS POSSIBLE' and start with

 EAST NORTHEAST'
 'WINDS 28 TO 33 KNOTS

Can you please help?
