Although euro's recent decline has resumed in part due to cross selling especially versus yen and sterling and marginal weakness below support at 1.3090 cannot be ruled out, loss of momentum should limit downside to 1.3040/50 and yield a corrective rebound later.  
Above 1.3235 (previous support) would signal a temporary low has been formed and bring retracement to 1.3290/00 but reckon resistance at 1.3338 (yesterday's high) would hold.
