I was working the R46 position combined at R47; with a CPC D-Side. The traffic volume at my sector was low; and there was a significant (more than 50% coverage) of weather in the airspace. I am one of the Feeder Sectors for the High Altitude Sectors (sitting behind me). The High Altitude Sector was extremely busy; with an extensive amount of weather and airplanes.The CIC was sitting next to him watching him work traffic. I overheard CPC saying; 'We need to slow this down; this is dangerous; and there's too much weather. We need this ground stopped.' Since I was working his Feeder Sector; I called Palm Beach and Miami and asked for a ground stop. Miami and Palm Beach complied. I turned around and told CIC that I ground stopped everything. He was busy engaged at R65; helping. A few minutes later; traffic management unit called CIC and asked why everything had been ground stopped. When he responded; they walked over and traffic management unit came in the area to argue why we can't ground stop traffic for safety; and how it wasn't dangerous in the first place.While CPC was still struggling to come out of the overloaded situation at R65/64/68 sector; traffic management unit called Miami and Palm Beach and resumed departures; without coordinating this with me at the sector; or with CPC.A few hours later; I asked FLM what I can do; and he said that we should do a report; but that he wouldn't initiate it. So [this report] is my only recourse. I believe that traffic management unit should not be able to coordinate restrictions that are less restrictive then what the sector is asking; without the sector's permission. In this case; I asked for a ground stop because I felt the situation was unsafe; by removing the ground stop without coordinating with me; they could have put Sector 65 in an even more unsafe situation.
Miami Center Controller reported a dangerous situation due to weather and traffic volume.
