Narrative:

After a go around at orlando due to WX and windshear, we were proceeding south to our divert at mlb. We had just broken out of the clouds at 3000 ft while being vectored south by patrick approach. They alerted us to traffic at our altitude, 10 O'clock position and 3 mi. A visual search proved useless. We then started getting a TCASII TA showing the traffic at 2-3 mi level and heading our way. This turned into an RA instructing us to climb. The copilot began to climb just as I spotted the bonanza at approximately 1 NM.. As we climbed, the bonanza took evasive action by turning hard right and flying behind us. We climbed approximately 1000 ft before the conflict and RA were resolved. We informed patrick approach of our actions and proceeded to mlb.
