  The Spanish Space Weather Service SeNMEs, \url{www.senmes.es}, is a portal
created by the SRG-SW of the Universidad de Alcal\'a, Spain, to meet societal
needs of near real-time space weather services. This webpage-portal is divided
in different sections to fulfill users needs about space weather effects: radio
blackouts, solar energetic particle events, geomagnetic storms and presence of
geomagnetically induced currents. In less than one year of activity, this
service has released a daily report concerning the solar current status and
interplanetary medium, informing about the chances of a solar perturbation to
hit the Earth's environment. There are also two different forecasting tools for
geomagnetic storms, and a daily ionospheric map. These tools allow us to
nowcast a variety of solar eruptive events and forecast geomagnetic storms and
their recovery, including a new local geomagnetic index, LDi{\~n}, along with
some specific new scaling. In this paper we also include a case study analysed
by SeNMEs. Using different high resolution and cadence data from space-borne
solar telescopes SDO, SOHO and GOES, along with ionospheric and geomagnetic
data, we describe the Sun-Earth feature chain for the event.
