"Activity has remained essentially unchanged. Intermittent small to moderate explosions occur from the volcano's summit crater, where slow magma extrusion continues to accumulate in a moderately viscous, flat dome. 

An aerial survey on 10 April showed that the most recent dome seen in February (numbered 55) had partially collapsed in its center, as a result of the explosions during late March to early April. Its remaining mass occupying the inner crater was flat and had developed a series of concentric fissures." (from volcano discovery website)
I suggest activity will remain VEI=2 until explosions make the lava dome collapse in the next days or weeks.

Be careful, volcanoes are still complicated to predict and wrong predictions are possible. Also, this is short term predictions. These are the most likely scenarios but everything is possible.

Activity continues at low levels, it fluctuates between VEI=1 and VEI=2, and it is accompannied at times by also fluctuating levels of tremor. It is associated with a flat lava dome inside the inner crater (250m in diameter and 30m thick). Activity is expected to remain VEI=2 until explosions make the lava dome collapse in the next days or weeks.

Be careful, volcanoes are still complicated to predict and wrong predictions are possible. Also, this is short term predictions. These are the most likely scenarios but everything is possible.

Strombolian activity continues, it sends ash plumes 2 km abve the volcano (see photo) and incandescent fragments as far as 700m from the crater (see photo). Moreover, strombolian acivity is accompannied by tremor and high earthquake activity (see here).

This VEI=2 activity is expected to continue with no significant changes.

Ashfall was reported in Tetela del Volcan, San Pedro Nexapa and Amecameca, and it may occur within a 20 km radius around the volcano.

Be careful, volcanoes are still complicated to predict and wrong predictions are possible. Also, this is short term predictions. These are the most likely scenarios but everything is possible.
