Recently reported diboson excesses at LHC are interpreted to be connected with heavy WW resonance with weak isotopic spin 2. The resonance appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant λ. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in inclusive production of W+W+, W+ (Z,γ), W+ W-, (Z,γ) (Z,γ), W- (Z,γ), W-W- resonances with MR ≃ 2 TeV, which could be reliably checked at the upgraded LHC with √(s) = 13 TeV. In the framework of an approach to the spontaneous generation of of the triple anomalous interaction its coupling constant is estimated to be λ= - 0.017± 0.005 in an agreement with existing restrictions.
