Wave #1 at 10:05 UTC Eastern Pacific discussion. This wave was introduced on May 8 so is two full weeks:
A tropical wave extends southward from southeastern Mexico along
across Mexico-Guatemala border into the Pacific Ocean near
02N92W, moving W at 5 to 10 kt. Scattered moderate convection is
evident from 08N to the Guatemala-El Salvador coast between 87W
and 98W.
Wave #2 at 12:05 UTC discussion:
An Atlantic Ocean tropical wave is along 58W/59W, from 13N
southward, moving westward at 15 to 20 knots. Although this wave
is weaker than it was several days ago, low level wind shifts were
noted on the past several upper air soundings from Cayenne,
French Guiana that are characteristic of a tropical wave passage
and this provides some confidence of the position of the wave.
This is supported by weak cyclonic turning noted in lower level
satellite vector winds near where the tropical wave axis is
analyzed. Trade wind convergence is supporting a line of weak
showers east of the tropical wave axis, from 07N to 09N between
53W and 58W.
