#TSJulia's wind and convection area now covers 2.4 million km, draging moisture off the Pacific Ocean over Panama & Costa Rica. Her outer rain bands extend from Colombia to Honduras - and she is not yet a hurricane.
While #TSJulia or #HurricaneJulia is not expected to last much longer, the #ExtremeWeather event associated with the storm is forecast to bring extreme/catastrophic weather across the entire region over the coming fortnight.
Accumulating rainfall forecast - 16 days. GFS Model
Exactly what will happen is far from clear as the forecasts keep changing but the combination of very high atmospheric water, and a massive arctic blast coming south (even pushing a small hurricane backwards down Mexico's Pacific Coast as you see here is not good.
The impact of the arctic blasts can be seen here coming in from the top of the image and pushing the atmospheric water south.
This run includes an atmospheric river event over Florida and a colossal Gulf of Tehuantepec gap wind event which could see hurricane force winds.
In the latest @NHC_Atlantic discussion of #TSJulia an earlier wind gap event is expected to play a role in disspation of the remnants of the storm.
The later wind gap event shows up in the PWAT forecast in the second image here.
But the big impact will be rain, flooding and land slides from Columbia to Mexico with much of the huge area forecast to receive 7-20 - inches of rain - with the possibility of up to 40 inches.
